Rscript -e 'summary(read.csv("data.csv"))'

Rscript runs R code from the command line without opening the interactive session. The -e flag takes code as a string: read.csv loads data.csv into a data frame, and summary prints min, quartiles, mean, max, and missing-value counts per column. This one-liner is the R equivalent of csvstat. For a single column, wrap it like summary of the column with the dollar sign syntax.
