[R] using an array of strings with strsplit, issue when including a space in split criteria
Dear all, I'm having a problem understanding why a split does not occur with in the 2nd use of the function strsplit below: # text strings> txt <- c("sales to 23 August 2008 published 29 August",+ "sales to 6 September 2008 published?11 September") # first use> strsplit(txt, 'published', fixed=TRUE)[[1]] [1] "sales to 23 August 2008 " " 29 August" [[2]] [1] "sales to 6 September 2008 " "?11 September" # second use, but with a space ' ' in the split> strsplit(txt, 'published ', fixed=TRUE)[[1]] [1] "sales to 23 August 2008 " "29 August" [[2]] [1] "sales to 6 September 2008 published?11 September" Thank you kindly for any help in advance.

I am using the exact same version of R as you also on Vista but can't reproduce your result. For me it splits properly. Try starting R like this (modify path if needed) from the Windows cmd line: \Program Files\R\R-2.9.2\bin\Rgui --vanilla and then try it.
