R describe和R Markdown

Question

I'd like to describe my data table in a R Markdown file using

xtable(data, type='html')

But none of the packages I looked so far seem to be compatible with xtable in html setting, fi Hmisc::describe , reporttools::tableNominal .

Does anyone have a solution for this?

Example: Something like Variables Overview with xtable in R but working in Markdown/html.

Answer 1

try pander package. specifically pandoc.table function from that package

> pandoc.table(head(mtcars), split.tables=Inf, style='rmarkdown')

That markdown table should render as follows

Answer 2

Ok, I've found one option that does work well with R markdown and that is using the psych::describe command. This has the advantage that the final table is a data.frame object that can then be further manipulated.

with xtable

library(psych)
library(xtable)
table.desc <- describe(mytable)
print(xtable(table.desc), type="html")

or using Gmisc

library(psych)
table.desc <- describe(mytable)
table.prep <- as.matrix(table.desc)
library(Gmisc)
htmlTable(table.prep)

Please note that in this example you do want to include the rownames, as they are part of the describe output. Also Gmisc inherits the Hmisc::describe command and has thus to be loaded AFTER creating the stats table.
