Hi,
Try this:
Vec[grepl("\\(",Vec)]<-paste0("-",gsub("[()]","",Vec[grepl("\\(",Vec)]))
as.numeric(Vec)
# [1] 0.036578077 -1.097386482 -0.812507787 0.577806996 -0.452456601
#[6] -1.890081260 -1.871609376 0.005521704 -0.476919233 -2.413301888

Subject: [R] Converting a character vector to numeric
Hello again,
Let say I have following vector:
Vec <- c("0.0365780769", "(1.09738648244378)", "(0.812507787221523)",
"0.5778069963", "(0.452456601362355)", "-1.8900812605", "-1.8716093762",
"0.0055217041", "-0.4769192333", "-2.4133018880")
Now I want to convert this vector to numeric vector. I am having
problem to doing so because there are some elements with "()" which
should be treated as negative.
Can somebody help me how to achieve that?
Thanks and regards,
