Hi all,
I have a large number of text strings to search for enumerated items.
However, I am receiving this error message even though I thought that I
properly escaped the special character closed parenthesis:
> Count<-str_count(text3,keywords)
Error in stri_count_regex(string, pattern, opts_regex = opts(pattern)) :
Syntax error in regexp pattern. (U_REGEX_RULE_SYNTAX)
===
Here is example code:
text1<-"This is a list:
1) Number 1
2) Etc
3) Etc"
text2<-"This is NOT a list:
Blah, blah, blah
Blah, blah, blah"
text3<-c(text1,text2)
text3
{keywords<-c(paste(0:9,"\\)"),paste(0:9,"\\)",sep=""),
paste(0:9,"."),paste(0:9,".",sep=""),"-","*")}
keywords
Count<-str_count(text3,keywords)
===
I am looking for Count<-c(3,0)
Any suggestions?
Thanks!
Dan
