I m replacing one text in R using sub.
x<-"My name is ${name}"
sub("${name}","Tiger",x)
Error Message:
Error in sub("${name}", "Tiger", x) :
invalid regular expression '${name}', reason 'Invalid contents of {}'
Input text has {}, How to fix this error?
$
, {
, and }
need to be escaped:
sub("\\$\\{name\\}","Tiger",x)
# [1] "My name is Tiger"
Use the fixed=TRUE
argument:
sub("${name}","Tiger",x, fixed=TRUE)
# [1] "My name is Tiger"
