Here is one way of solving it:
> x <- c('0(a=1)' ,'0(b=1)' ,'0.133(b=1)' ,'0.555(a=1)'
,'>5.32(a=1)')
> # "(" and ")" have special meaning in regular expressions so they have to
be escaped
> (y <- as.numeric(gsub("\\(.*\\ )|>", "", x)))
[1] 0.000 0.000 0.133 0.555 5.320
> # find "a=1" to div
Dear all,
I need to clean up one variables in a dataset.
e.g. lets say the dataset is "trial", the variable for cleaning up is "V1"
>trial$V1
[1] 0(a=1) 0(b=1) 0.133(b=1) 0.555(a=1) >5.32(a=1)
what i need to do is to remove the text (a=1) and (b=1) and the ">" in the
V1, and then convert to a
2 matches
