[R] comma as a seperator to numeric

[Mat]

Hello together,

i have a big problem, to convert a column in my data.frame to numeric.

I have:
61,13 in the column and write:
data$PT_DL<-as.numeric(as.character(data$PT_DL))

the result is NA, not a point seperated number.

How can i change the data to an as.numeric number?

Thank you for your help.

Mat
