use caption and subcaption packages for side by side figures and tables.
1. use #capture.output# to save results of summaries or of models as in write.table(capture.output(summary(a model object)), ‘temp.txt’, quote=FALSE, sep = ‘\n’)
2. using the results in R-studio .Rnw files, use package TEXREG. If there are underscores, then use “\catcode`\_=12” with a T1-fontenc, to not have to explicitly escape the underscore characters everytime
