how to get value when a variable name is passed as a string

So I’m using assign() to create a variable

nam <- "act01"
assign(nam, read.table(text.txt, sep = ", ", header = T))

and I’m trying to append the act01 variable just created into another list

acts = list()
acts[[1]] <- nam  # something wrong here, I can't find a way to retrieve the variable

Is there any function that allows you to convert the string into a variable in R?

Thanks alot

Too much work; just write

list()->acts
acts[[1]]<-read.table(text.txt, sep = ", ", header = T)

or better

acts<-lapply(text.txts,read.table,sep=', ',header=T)

where text.txts is a vector of your files, made for instance by list.files().
