R help - Sep 2022 - Remove line from data file

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?

DFP (iPad)

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")
