[R] using an array of strings with strsplit, issue when including a space in split criteria

[Juliet Hannah]

I get a different result:

txt <- c("sales to 23 August 2008 published 29 August","sales to 6
September 2008 published 11 September")
strsplit(txt, 'published ', fixed=TRUE)
[[1]]
[1] "sales to 23 August 2008 " "29 August"

[[2]]
[1] "sales to 6 September 2008 " "11 September"
