Thank you for your reply.  I meant from the dataframe, but that�s one of the 
terms I had forgotten.  I created that from read.csv, the csv file coming from 
Excel.  Last night I went ahead and made the change(s) using Excel.

For future reference, when I look at your solutions below, what do you mean by 
�value to delete�?  Could that just be a row number?  I was wanting to delete 
something like the 18th row in the dataframe?

From the file? Or the data frame once its loaded?

What format is the file? CSV?

Do you know the line that needs deleted?

mydf <- read.csv("myfile.csv")

mydf2 <- mydf[-columnName == "valuetodelete", ]
# Note the - infront of column name
# or perhaps columnName != "value to delete", ]

write.csv(mydf2, "mydeletedfile.csv")

that?
