is.na in R – How to Find NA values in R. The first step of the process is detecting missing values in our data when they occur. This is accomplished using the function is.na in R. # is.na in R example test <- c(1,2,3,NA) is.na(test) This function will return a vector of True / False values indicating if the values of a vector are missing.

In this example, we will create a data frame with some of the rows containing NAs. > DF1 = data.frame(x = c(9, NA, 7, 4), y = c(4, NA, NA, 21)) > DF1 x y 1 9 4 2 NA NA 3 7 NA 4 4 21.

removeClass:null;return b}function Ha(a,b,c){function d(a){S(a)&&(a=a.split(" ")); var r={addClass:"",removeClass:""};p(e,function(b,c){var d,e isString,na=u.

Function to remove rows containing NAs from a data vector or matrix. Also counts the number of rows remaining, the number of rows deleted, and in the case of a matrix the number of columns. The results are returned in a list for subsequent processing in the calling function.
