I know the following is documented behaviour, in the sense that the
help page for as.character mentions that it truncates at about 500
characters... but wouldn't it be better if there was a warning of
some sort issued? Or am I misunderstanding what's happening here?
> str <- sample(LETTERS,301, replace=TRUE)
> search.list <- list(str[-301],str)
> item <- list(str) # == search.list[2]
> match(item, search.list)
[1] 1
> item <- list(str[1:299])
> match(item, search.list)
[1] 1
> item <- list(str[1:29])
> match(item, search.list)
[1] NA
> version$version.string
[1] "R version 2.7.1 (2008-06-23)"
Thanks.
