What OS are you using?  When you say the list is in a text file, how  
is the text file structured, e.g. CSV, TSV, fixed-width, other?

Here's an example of creating, writing, and reading a data.frame:

d <- data.frame(cbind(x=1, y=1:10))
write.table(d, file="r-data.txt", sep="\t", na="", quote=FALSE,  
row.names = FALSE)
d.new <- read.delim("r-data.txt")

HTH.
