Methods include converting series of event names to strings, finding common patterns in a group of strings, discovering featured patterns when comparing two groups of strings as well as the number and starting position of each pattern in each string, obtaining transition matrix, computing transition entropy, statistically comparing the difference between two groups of strings, and clustering string groups. Event names can be any action names or labels such as events in log files or areas of interest (AOIs) in eye tracking research.
Quantify patterns in a group of strings and comparison between two groups of strings.
Add function EveS.
Change the name of function 'UniPatterns' to 'FeaturedPatt'.
Functions CommonPatt and CommonPattern: column names with '_total' changed to '_grp'.
Function StrKclust: update cluter plot
Add functions DupRm, StrHclust, StrKclust, TransEntro, and TransEntropy.
Functions TransInfo and TransMx: strings with length < 2 are ignored for transitions.

Correct misspellings in some .Rd files.
Add function TransMx.
Function CommonPattern: the file that contains all possible substrings is no longer exported.
