[R] Reading multiple txt files into one data frame

Hello All,

I have a device that spews out experimental data as a series of text files each of which contains one column with several rows of numeric data. My problem is that for each trial it gives me one text file (and I run between 30 to 50 trials at a time) and I would ideally like to merge all these text files into one large data frame with each column representing a single trial. It is not a problem if NA characters are added to make all the columna of eaqual length. Right now I am doing this by opening each file individually and cutting and pasting the data into an excel file. How can I do this in R assuming all my text files are in one directory.

Is it also possible to customize the column headers. For example if I have 32 trials and 16 are experimental and 16 are control and I want to name the columns "Expt1", Expt2",... "Expt16" and the control columns "Cntl1",...Cntl16".
