docs: fix grammar 'can also computed' in collapse_and_plm.Rmd

[LeonidasZhak]

Summary

Fixed a grammar error in the vignette where "can also computed" was used instead of "can also compute".

Problem

Line 1243 of stated:

It computes a default set of 5 statistics (N, mean, sd, min and max) and can also computed higher moments (skewness and kurtosis)

"can also computed" is grammatically incorrect. The modal verb "can" requires the bare infinitive "compute", not the past participle "computed".

Fix

Changed to .

Validation

• Change is purely documentation (no code changes)
• The fix is in the section about , which is inspired by Stata's command

Stata Migration Relevance

This fix improves the readability of the documentation in the panel data vignette, which is directly relevant for Stata migrants learning about panel data summary statistics in R. The function is modeled after Stata's and commands.
