Count non na in r

Say I have the following R data.frame ZZZ: ( ZZZ <- structure (list (n = c (1, 2, NA), m = c (6, NA, NA), o = c (7, 8, 8)), .Names = c ("n", "m", "o"), row.names = c (NA, -3L), class = "data.frame") ) ## not run n m o 1 1 6 7 2 2 NA 8 3 NA NA 8. colSums (is.na( data)) # x1 x2 x3 # 2 1 0. colSums (is.na (data)) # x1 x2 x3 # 2 1 0. The RStudio console output shows the number of NA values for each of our variables. The variable x1 contains 2 NA values, the variable x2 contains 1 NA value, and the variable x3 contains no NA values. library (raster) r <- raster(nrows=20, ncols=10) r[] <- runif(ncell(r)) r[sample(1:ncell(r),10)] <- NA ( r <- as.matrix(r) ) # Count number of NA values apply(r, MARGIN = 1, FUN = function(x) length(x[is.na(x)]) ) # Calculate "true" n, accounting for NA's apply(r, MARGIN = 1, FUN = function(x) length(x[!is.na(x)]) ) R is.na Function Example (remove, replace, count, if else, is not NA) Well, I guess it goes without saying that NA values decrease the quality of our data.

That’s basically the question “how many NAs are there in each column of my dataframe”? This post demonstrates some ways to answer this question. Way 1: using sapply You can count the NAs in each row with this command: rowSums(is.na(dat)) where dat is the name of your data frame.

In fillna 29 Mar 2021 Been poking around R source code a whole lot. Is it intentional that the inherits does not actually reflect the S3 dispatch chain of implicit classes? 8 Apr 2021 Dropping all the NA from the data is easy but it does not mean it is the most elegant solution. During analysis, it is wise to use variety of 30 Jun 2017 Hello, I wan to write a program to count missing and non missing values across the columns. I got a program from someone like this- data temp; In the second case, it tries to check if x is `NA, but there is no value to be checked.

Fortunately, the R programming language provides us with a function that helps us to deal with such missing data: the is.na function .

User rrs answer is right but that only tells you the number of NA values in the particular column of the data frame that you are passing to get the number of NA values for the whole data frame try this: apply (, 2, function (x) {sum (is.na (x))}) This does the trick.
