Help with regular expressions
Hi Dennis,
How about:
# define the two values to search for
x<-2
y<-3
# create your search string and replacement string
repstring<-paste(x,y,sep=",")
newstring<-paste(x,y,sep=".")
# this is the string that you want to change
thetastring<-"SIGMA(2,3)"
sub(repstring,newstring,thetastring)
[1] "SIGMA(2.3)"
Use gsub if you want to change multiple values
