News

loon 1.2.1

  • updated loonGrob() and grid.loon()
    • provide more meaningful grobs (including better descriptions and more informative "empty" grobs).
    • added condGrob() to effect the conditional construction of either the desired grob (if it is visible in the loon plot) or the empty grob as placeholder containing relevant arguments
  • introduced the method plot.loon() so that plot(p) of a loon plot p will now draw the corresponding grid object on the current device

loon 1.2.0

  • added loonGrob() and grid.loon() functionality

    • any loon plot can now be converted and saved as a grid graphics object
    • permits printing/exporting snapshots of loon plots in documentation
    • S3 class structure extended to more loon plots
  • l_compound classes introduced to ease user creation of complex layouts

    • includes simple programming interface to extend loonGrob() to any user-defined
    • converted current compound layouts to new l_compound model (e.g. l_pairs, l_stl)
    • l_getPlots which returns a list of the loon plots in the display (works for simple loon plots too)
    • l_getLocations which returns a matrix showing the location of the loon plots (in order) (works for simple loon plots too)
    • l_get_arrangeGrobArgs which returns the arguments and their values to be passed on to arrangeGrob() (from gridExtra) to allow arbitrary layout by the user.
      • this is NOT implemented for simple loon plots (but could perhaps be)
    • loonGrob_layoutType which returns a string indicating whether "location" or "arrangeGrobArgs" are to be used when creating a grid version of the l_compound. (default is "locations", other possibility is "arrangeGrobArgs"
  • Fixed widget handle class order: specific classes first.

  • l_hexcolor.R

  • l_plot_decomposed_ts

  • l_cget and l_configure are now a generics with methods for objects of class loon, character, and l_compound.

  • New functions l_getOption, l_getOptionNames, l_userOptions, l_userOptionDefault, l_setOption

  • New function l_primitiveGlyphs

  • names for loon object handles to print out the state names. l_state_names can be used alternatively

loon 1.1.0

  • first release on CRAN
  • change state names
    • itemlabel to itemLabel
    • showItemlabels to showItemLabels
  • automatically convert nested lists and data.frames
    • unexported l_nestedTclList2Rlist and l_data
  • remove the local copy of the website and make l_help point to the official website.

loon 1.0.1

  • Bug fix in geodesic2d for 4d transitions

loon 0.9.1

  • Bug fix when layering maps (sp classes) with asSingleLayer=TRUE
  • Bug fix in scale_image

loon 0.9

  • initial beta release for the general public
