[R] strsplit with invalid regular expression

[Bharat Warule]

Hi all,

> diff_operator <- "\\("
> strsplit(cond, 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
