ezpickr
Easy Data Import Using GUI File Picker
Choosing any rectangular data file using interactive GUI dialog box, and seamlessly manipulating tidy data between an 'Excel' window and R session.
The goal of ezpickr is to provide R beginners with a convenient way to
pick up their data files and to easily import it as a tidy tibble form
into an R environment using GUI file-picker dialogue box (through
ezpickr::pick()), and to provide R users with a convenient way to open
and manipulate their data objects using Excel application for a seamless
data communication between an Excel window and R session through
ezpickr::viewxl()).
You can alternatively use ezpickr::pick() function for choosing *.csv,
*.csv2, *.tsv, *.txt, *.xls, *.xlsx, *.json, *.html, *.htm, *.php,
*.pdf, *.doc, *.docx, *.rtf, *.RData, *.Rda, *.RDS, *.sav (SPSS), *.por,
*.sas7bdat, *.sas7bcat, *.dta, *.xpt, and *.mbox files in an interactive
GUI mode A file choose dialog box will be prompted.
Any additional arguments available for each file type and extension:
readr::read_csv() for CSV (Comma-Separated Values) files;
readr::read_csv2() for CSV2 (Semicolon-Separated Values) files;
readr::read_tsv() for ‘TSV’ (Tab-Separated Values) files;
readr::read_file() for ‘txt’ (plain text) files;
readxl::read_excel() for ‘Excel’ files; haven::read_spss() for
‘SPSS’ files; haven::read_stata() for ‘Stata’ files;
haven::read_sas() for ‘SAS’ files; textreadr::read_document() for
‘Microsoft Word’, ‘PDF’, ‘RTF’, ‘HTML’, ‘HTM’, and ‘PHP’ files;
jsonlite::fromJSON() for ‘JSON’ files; mboxr::read_mbox() for ‘mbox’
files; base::readRDS() for ‘RDS’ files; base::load() for ‘RDA’ and
‘RDATA’ files.
Each corresponding function depending upon a file extension will be automatically matched and applied once you pick up your file using either the GUI-file-chooser dialog box or explicit path/to/filename.

Example
Usage of the pick() Function
This is a basic example which shows you how to import data files:
library(ezpickr)# Choosing file and saving it into a variable## Scenario 1: Picking up a file using interactive GUI dialog box:data <- pick() ## Please use `picko()` instead if your path/file contains any Korean characters.## Scenario 2: Picking up a file using an explicit file name ("test.sav" in the example below; however, you can feed other files through this function such as *.SAS, *.DTA, *.csv, *.csv2, *.tsv, *.xlsx, *.txt, *.html, webpage URL, *.json, *.Rda, *.Rdata, and more):data <- pick("test.sav") ## Please use `picko("test.sav")` instead if your path/file contains any Korean characters.# Now you can use the imported file as a tibble data frame.str(data)
Usage of the viewxl() Function
You can open any data.frame, tibble, matrix, table or vector from an R session into your default-set spreadsheet application window as follows:
library(ezpickr)data(airquality)str(airquality)# Use `viewxl()` function to open your data object in your spreadsheet:viewxl(airquality)# Then, when necessary, you can modify the opened data in the spreadsheet and save it as a new data.# You can pass a list object to the `viewxl()` function like below:l <- list(iris = iris, mtcars = mtcars, chickwts = chickwts, quakes = quakes)viewxl(l)# Then, each list item will appear in your Excel window sheet by sheet.
News
ezpickr 1.0.5
pick()andpicko()functions now allow users to specify value-separator parameter usingdelimoption for*.csv,*.csv2, and*.tsvfiles when the expected delimitters are not used. For example, in any event your csv file is separating each value using whitespace instead of comma(,) do the following:
data <- pick(delim=" ")
ezpickr 1.0.4
- "xpt" file format is now supported in
pick()function. - Atomic class (vector) is now supported in
viewxl()function.
ezpickr 1.0.3
- A critical bug that users cannot use the additional arguments of
readxl::read_excel()for an Excel format within bothpick()andpicko()functions has been resolved; by default an Excel file with multiple sheets is returned as a list object when users have not passed any additional arguments.
ezpickr 1.0.2
purrrpackage has been added to the import package list to efficiently return multiple Excel sheets as a list of tibble; this way offers a better performance than the previouslapply()mechanism.- Users can now access a multi-sheet Excel file with each sheet name as well as its index number when using
pick()andpicko()functions. - A bug that users cannot utilize explicit Korean path/file when
modeoption is specified inpick()function has been resolved; Korean users now can use explicit Korean-included path/file inpicko()function as well. view()function is now deprecated to avoid any collision withtibble::view()function which has the same name; users is recommended to useviewxl()function in the future instead.view()andviewxl()functions now return a tibble object reflecting users' real-time manipulation done in Excel.view()andviewxl()functions have been fixed to process multiple sheets as a list object.mboxfile format is now supported in bothpick()andpicko()functions usingmboxr::read_mbox()function under the hood.
ezpickr 1.0.1
- New function
picko()has been added to assist Korean R users in importing Korean-includedpath/to/fileas an alternative ofpick()function; other non-Korean R users can still employ the existingpick()function. - A more robust mechanism has been applied to a file path that contains any Korean characters.
pick()andpicko()functions now automatically return an Excel file that contains more than one sheet as a list of each Work Sheet (Thanks hyun seung Lee for the suggestion via email).view()function now internally employswritexl::write_xlsx()function instead ofreadr::write_csv()to create Microsoft Excel file to provide users with a stable encoding consistency; since this change,modeoption of theview()function has been removed.tableclass is now supported inview()function by automatically converting it into data.frame class.- Startup message has been added to the package so that Korean R users can benefit from the newly developed
picko()function when interacting with Korean-included dataset.
ezpickr 1.0.0
modeargument has been added topick()function to accommodate Korean R users' needs in terms of R session locale and encoding to Korean. Available values include "ko1" for "CP949" and "ko2" for "UTF-8" while both change R locale into Korean.view()function has been newly added to provide R beginners with a convenient way to place their data in a spread sheet application.

airquality.savfor an example purpose. - Now
pick()function returns a JSON file into a tibble form. - Returning a tibble form for RDA, RData, and RDS as well when
pick()function is applied.
