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

Using tidyverse/dplyr, you can also remove rows with any zero value in a subset of variables:

# variables starting with Mac must be non-zero
filter_at(df, vars(starts_with("Mac")), all_vars((.) != 0))

# variables x, y, and z must be non-zero
filter_at(df, vars(x, y, z), all_vars((.) != 0))

# all numeric variables must be non-zero
filter_if(df, is.numeric, all_vars((.) != 0))
