Package openxlsx not installed when running "make output/barplot.png"

Again, seems to be the same issue: 

make output/barplot.png
Rscript code/00_clean_data.R
Error in library(openxlsx) : there is no package called ‘openxlsx’
Execution halted
make: *** [output/data_clean.rds] Error 1

I will install the package and try again.
