Hi,
You could also try:
gsub("[()]","",names(dataFrame))
set.seed(15)
datF<- data.frame(sample(1:10,15,replace=TRUE))
names(datF)<- "fBodyGyroskewness()Z"
gsub("[()]","",names(datF))
#[1] "fBodyGyroskewnessZ"
sub("\\(\\)","",names(datF))
#[1] "fBodyGyroskewnessZ"
A.K.

Subject: Re: [R] Dealing with parentheses within variable names
Oops -- forgot that you have to double the backslashes:
So use:
sub("\\(\\)","", names(dataFrame))
