Hi, welcome to the R-help list
This help list does not accept html coded messages and so nothing meaningful seems to have come through.
If you aready have the data loaded into R please supply some sample data
The easiest way to supply data is to use the dput() function. Example with your file named "testfile":
Then copy the output and paste into your email. For large data sets, you can just supply a representative sample. Usually, dput(head(testfile, 100)) will be sufficient.
Otherwise perhaps you could mock up some data or place a file as some place such as mediafire or dropbox where readers can access it.
Here is a link that suggests some ways to ask a good question on the list https://github.com/hadley/devtools/wiki/Reproducibility
The more you follow the suggestions and provide meaningfull examples, code or general information about your installation the faster people may be able to help you.
