Dear Bert,
The variable patt does not exist in the R environment.
I was pasting the code for an R function in the R console and I had a
syntax error on a line. But the next lines executed simply as simple R
code. The variable patt was not previously defined.
Though x was a different object
Dear Andrew,
I screwed it a little bit up. The object was not a string vector, but an
xml object (the original xml with the abstracts).
str(x)
List of 2
$ node:
$ doc :
- attr(*, "class")= chr [1:2] "xml_document" "xml_node"
i pasted the R code for a function but had an error, which stop
Dear R Users,
I have run the following command in R:
# x = larger vector of strings (1200 Pubmed abstracts);
# patt = not defined;
npos = regexpr(patt, x, perl=TRUE);
# Error in regexpr(patt, x, perl = TRUE) : object 'patt' not found
The problem:
R becomes unresponsive and it takes 1-2 minut
