Add a column with count of NAs and Mean

Question

I have a data frame and I need to add another column to it which shows the count of NAs in all the other columns for that row and also the mean of the non-NA values. I think

Answer 1

You can try this:

#Find the row mean and add it to a new column in the dataframe
df1$Mean <- rowMeans(df1, na.rm = TRUE)

#Find the count of NA and add it to a new column in the dataframe
df1$CountNa <- rowSums(apply(is.na(df1), 2, as.numeric))
