Removing rows of a matrix with at least one NA in R

Question

I am trying to remove the rows of a matrix in R. My criteria for row removal is that the column contains at least one NA (note that the entire row does not need to be NA like in other questions on this site).

For example, if matrix A looks like the following

32  54  34
NA  10  NA
17  93  NA

Only the first row should remain.

This is what I am trying, but I am getting a column instead of a row.

newMatrix <- A[,rowSums(apply(A, 1, is.na))<1]
#A is a matrix

What am I missing? I tried doing !is.na, but R didn't like that.

Answer 1

Did you try: matrix[complete.cases(matrix),]
