[R] formatting column names of data frame

[John Kane]

As Rainer Schuermann says, use the xtable package. Have a look at the documentation entitled xtable gallary --available at your friendly neigbourhood CRAN site and have a look at section 3.1. and it's probably a good idea to look at ?print.xtable as well

You might also what to have a look at the latex function in Hmisc.

Here is an example with "Average" in bold. It ran for me using LyX and knitr rather than Sweave.
###==================================
library( xtable ) 
x <- structure(list(Record = 1:3, Average = c(34L, 14L, 433L), Maximum = c(899L, 15L, 1003L)), .Names = c("Record", "Average", "Maximum"), class = "data.frame", row.names = c(NA, -3L)) 
names(x)  <-  c("Record", "\\textbf{Average}", "Maximum")
x <- xtable( x ) 
print( x,  sanitize.text.function = function(x){x} )
###==================================
