Skipping last column in R while `read.csv` should be done in two steps
data <- read.csv("test12.csv")
data
data[,-ncol(data)]
That is when you don't know the number of columns. If you explicitly know, use the code below instead:
df <- read.csv("test12.csv")[,-3]
This solution come from a stackoverflow post I did https://stackoverflow.com/questions/48597844/skipping-last-column-in-r-with-read-csv & could be related to another ask such as https://stackoverflow.com/questions/5788117/only-read-selected-columns to only read selected columns in R. (not from me this time)
