[R] Help with replacing a substring in a string

[Martyn Byng]

Hi,

Have you tried gsub?

> a = "abc.degg.hijk"
> gsub("."," ",a,fixed=TRUE)
[1] "abc degg hijk"

Dear R Users,

I am trying to replace a substring in a string with something else.

For example:
if we have "abc.degg.hijk"
I would like to replace all the "." with a SPACE to become
"abc degg hijk"

I have tried the replace.substring.wild function in the Hmisc package
but get this error:

> replace.substring.wild("abc.degg.hijk","*.*"," ")
Error in replace.substring.wild("abc.degg.hijk", "*.*", " ") :
  does not handle > 1 * in old
>

Can't really figure out from the function description or the error
message what I am doing wrong.

Any assistance would be appreciated, thanks in advance.

Regards,
Tolga
