Hello, Try something like the following.
ix <- which(c("601", "604") %in% rownames(data)) clean <- data[-ix, ] Hope this helps, Rui Barradas Citando Pauline Laïlle <pauline.lai...@gmail.com>:
Dear all, I built a dataframe with read.csv2(). Initially, row names are integers (order of answers to a survey). They are listed in the csv's first column. The import works well and my dataframe looks like I wanted it to look. Row names go as follows : [1] "6" "29" "31" "32" "52" "55" "63" "71" "72" "80" "88" "89" "91" "93" "105" "110" "111" "117" "119" "120" [21] "122" "127" "128" "133" "137" "140" "163" "165" "167" "169" "177" "178" "179" "184" "186" "192" "193" "200" "201" "228" etc. I would like to drop rows "601" & "604" to clean the dataframe. While data["601",] shows me the first row i'd like to drop, data[-"601",] returns the following : Error in -"601" : invalid argument to unary operator idem with data[c("601","604"),] and data[-c("601","604"),] It is the first time that I run into this specific error. After reading a bit about it I still don't understand what it means and how to fix it. Thanks for reading! Best, Pauline.
