How to remove rows with any zero value

Question

I have a problem to solve how to remove rows with a Zero value in R. In others hand, I can use na.omit() to delete all the NA values or use complete.cases

Answer 1

You can use filter from dplyr package.

Let's call your data frame df

library(dplyr) df1 <- filter(df, Mac1 > 0, Mac2 > 0, Mac3 > 0, Mac4 > 0)

df1 will have only rows with entries above zero. Hope this helps.

Answer 2

I prefer a simple adaptation of csgillespie's method, foregoing the need of a function definition:

d[apply(d!=0, 1, all),]

where d is your data frame.
