How to replace 'star (*)' with blank space?
3 messages · Ruby Chu, Uwe Ligges, David Winsemius
gsub("\\*", " ",x)
should do. Please read about regular expression as used by gsub().

Hi There
I'm not very sure how to replace the stars in a character vector
For example:
a character vector (n rows by 1 col)
[1] "-27 -21 -25 -28**** ***** -29"
[2] "-27 ******** -28**** ***** -29"
.
.
.
.
.
.
[n] "-1***********************************"
I wish to replace all the *s with a blank, result as per below
[1] "-27 -21 -25 -28 -29"
[2] "-27 -28 -29"
.
.
.
.
.
.
[n] "-1 "
I have tried to use gsub( )
like: gsub("*", "", x)
but doesn't seem to be working...please advise
Thank you

"*" is an operator in regex, so you need to double escape it in the
pattern argument (but may not need to escape it in the replace argument.
> gsub("\\*", "", "test8888****8888****9999")
[1] "test888888889999"
> gsub("\\.", "*", "test8888...8888...9999")
[1] "test8888***8888***9999"
but doesn't seem to be working...please advise Thank you Ruby [[alternative HTML version deleted]]
