[R] How to Read source code of function as string vector or matrix
Hi,
I need to read source code of function as a string vector or matrix.
if i am using get method it return as closure type.
example
readcsv<-function(filepath)
{
output<-read.csv(filepath)
}
how to get as string vector like this
test[1]=readcsv<-function(filepath)
test[2]={
test[3]=output<-read.csv(filepath)
test[4]=}
Thanks
