Although I am not an expert, this is simple.

txt<-  "LOI ."
gsub(".","%",txt, fixed=TRUE)

Re: [R] find and replace characters in a string

Hello,

The period is a metacharacter so you have to escape it.
The period is escaped with a '\'. In it's turn, '\' is a metacharacter 
so it needs to be escaped. Hence the double'\\'.


x <- "LOI ."
gsub("\\.", "(%)", x)


Hope this helps,

Rui Barradas

Hi,

I have a string of text as follows "LOI ."

How do I replace the dot with "(%)"

gsub(".","(%)",LOI .)

gives

"(%)(%)(%)(%)(%)"

Thanks

Hi,

I have a string of text as follows "LOI ."

How do I replace the dot with "(%)"

gsub(".","(%)",LOI .)

gives

"(%)(%)(%)(%)(%)"

Thanks
