For this, we have to exchange the colSums function by the rowSums function:rowSums(!is.na(data)) # Get number of non-NA values in rows # [1] 2 1 1 0 1 2The previously shown vector shows the number of non-NA values in each of the six rows in our data frame....
x=="c"# Equivalent to Excel's IF# [1] FALSE TRUE FALSE TRUE FALSE FALSE TRUE The previous R code has returned a logical vector to the RStudio console, indicating which elements of our data are equal to the letter “c”. We can now wrap thesum functionaround this code to get the ...
