I keep finding myself in a situation where I want to calculate a
variable name and then use it on the left hand side of an assignment.
iteration <- 1
varName <- paste("run",iteration,sep="")
myList$parse(text=varName) <- aColumn
I want to take some existing variable "aColumn" and use the name
"varName" name for it and put it into a list "myList". That use fails
with this error:
Error: couldn't find function "(<-"
I've tried many variations on the theme.
If I could do this with a data frame, I would be just as happy. Right
now I'm using a list rather than a data frame because not all columns
are of the same length. But I can work around that.
