knit both handout and presentation version of .Rnw slides with (relatively) good TeX error logging

if(!requireNamespace("remotes", quitly=TRUE)) install.packages("remotes")
remotes::install_github("brry/knitPres")

library("knitPres")
?knit_hand_pres

knit_hand_pres("SomePresentation.Rnw")

SomePresentation SP.Rnw should contain the handout option in it's first line:
\documentclass[handout]{beamer}

This will generate the files SP.pdf, SP.tex et al., SP.knitlog and SP_pres.pdf.

• get_texlog_warnings to get messages from (La)TeX log files via helper function get_from_log
• knit_hand_pres to knit both versions in parallel (handout and presentation)

Presentation templates with berryFunctions::createPres.
