C++ STL std:count() functionThe C++ STL contains the function std::count(), which is used to find the occurrence of the particular element in the given range. You can use this function with an array, string, vector, etc. To use this function, we have to use either <bits/stdc++> ...

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 ...
