Subject: [R] strsplit with invalid regular expression
Hi all,
> diff_operator <- "\\("

[[1]]
[1] "andsin" "log_angle_1_4)"
> diff_operator <- "\\sin("
> strsplit(cond, diff_operator)
Error in strsplit(cond, diff_operator) :
invalid regular expression '\sin(', reason 'Missing ')''
When I am going to split with "(" it’s working fine but when i want use
"sin(" this is not working.
I understand that, I am missing something can anybody please point me.
Thanks for your help.
Thanks,
Bharat
