Thank you for your reply. I meant from the dataframe, but t
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?

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
I’ve been retired since ‘06 and have forgotten most of R. Now I have a use for
it. I’ve created a data file and need to delete one row from it. How do I do
that?
