Remove Rows with Any Zero Value in R (Example)

 

In this tutorial, I’ll illustrate how to delete data frame rows where at least one value is equal to zero in the R programming language.

Creation of Exemplifying Data

Consider the following example data:

data <- data.frame(x1 = 5:0,                                      # Create example data
                   x2 = c(3, 1, 0, 2, 2, 7),
                   x3 = 5,
                   x4 = c(9, 0, 9, 9, 9, 0))
data                                                              # Print example data
#   x1 x2 x3 x4
# 1  5  3  5  9
# 2  4  1  5  0
# 3  3  0  5  9
# 4  2  2  5  9
# 5  1  2  5  9
# 6  0  7  5  0

Have a look at the previous RStudio console output. It shows that our example data has six rows and four columns. Some of the variables of our example data contain zero values.

 

Example: Removing Rows with Zeros Using apply() & all() Functions

This example shows how to get rid of all rows with at least one zero value using the apply and all functions in R.

Have a look at the following R code:

data_zero <- data[apply(data, 1, function(row) all(row !=0 )), ]  # Remove zero-rows
data_zero                                                         # Print updated data
#   x1 x2 x3 x4
# 1  5  3  5  9
# 4  2  2  5  9
# 5  1  2  5  9

The previous R code returns our new data frame to the RStudio console. As you can see, all rows containing zeros were removed.
