r - Change default alignment in pander (pandoc.table) -

-

i switching pander of knitr-markdown formatting, because provides such great pandoc support. 1 of things not happy default center-alignment. marketing people may love it, technical reports horror.

the best choice used hmisc use left alignment texts , dates default, , right alignment number of type.

is there simple way globally set in pander?

library(pander) pander(data.frame(      name          = letters[1:3],      size          = 1:3,      we.have.dates = sys.date() - 1:3  ))

thanks kind words , great question. there's not yet documented feature in pander, can pass r function default table alignment. quick demo:

> panderoptions('table.alignment.default', +     function(df) ifelse(sapply(df, is.numeric), 'right', 'left')) > pander(data.frame( +     name          = letters[1:3], +     size          = 1:3, +     we.have.dates = sys.date() - 1:3 + ))  ----------------------------- name     size we.have.dates   ------ ------ ---------------           1 2014-11-18       b           2 2014-11-17       c           3 2014-11-16      -----------------------------

so trick here define function takes 1 argument analysed, , returns vector of column alignment parameters.
