sumNA {relevance} | R Documentation |
Count the missing or non-finite values for each column of a matrix or data.frame
sumNA(object, inf = TRUE)
object |
a vector, matrix, or data.frame |
inf |
if TRUE, Inf and NaN values are counted along with NAs |
numerical vector containing the missing value counts for each column
This is a simple shortcut for apply(is.na(object),2,sum)
or apply(!is.finite(object),2,sum)

t.d <- data.frame(V1=c(1,2,NA,4), V2=c(11,12,13,Inf), V3=c(21,NA,23,Inf))
