sr.strsplit: Split a vector of strings by a single character

Description

Split a character vector using the sep argument. Results will be a vector, matrix, or list, depending on the value of collapse and drop.

Usage

sr.strsplit(strings, sep=" ", collapse=FALSE, drop=TRUE)

Arguments

strings

character vector

sep

single character to separate the strings

collapse

If collapse is TRUE, then sr.strsplit will attempt to 'collapse' the results into a matrix. This will only succeed, when all of the input strings split into the same number of sub-strings.

drop

If drop is FALSE and the length of strings is 1, sr.strplit will keep the result in either list or matrix format (depending on the value of collapse). By default, if strings as length 1, sr.strsplit's result is a simple vector.

Value

• a list, matrix, or vector of the split results of the strings supplied

Details

Differences between S-PLUS and R:

- multicharacter sep values (e.g. " " and "abc") are honored in R, but only the first character is honored in S-PLUS

- After splitting, S-PLUS removes leading and trailing whitespace characters (space, tab, and newlines)

Examples

x <- c("str:split" , "new:string")
split <- sr.strsplit(x, sep = ":")
## split has the value:
##[[1]]:
##[1] "str"   "split"
##
##[[2]]:
##[1] "new"    "string"

split <- sr.strsplit(x, sep = ":", collapse = TRUE)
## split has the value:
##      [,1]     [,2] 
##[1,] "str" "split" 
##[2,] "new" "string"

y <- "str:split"
split <- sr.strsplit(y, sep = ":")
## split has the value:
##[1] "str"   "split"
