[R] Math characters in column heading using latex() in Hmisc

[Ista Zahn]

Hi Christain,
You do not give us a reproducible example, nor do yo tell us how you
are creating the table. The following works fine for me:

dat <- data.frame(x1=1, x2=2, x3=3, x4=4)
names(dat) <- c("$\\sum_{i}\\sum_{j}C_{P,i,j,y}\\times\\mathit{FC}_{i}$",
"$XU_{alt,y}$","$n$","$\\bar{C}_{P,y}$")

library(Hmisc)
latex(dat)

on

R version 2.12.2 (2011-02-25)
Platform: i686-pc-linux-gnu (32-bit)

locale:
 [1] LC_CTYPE=en_US.utf8       LC_NUMERIC=C
 [3] LC_TIME=en_US.utf8        LC_COLLATE=en_US.utf8
 [5] LC_MONETARY=C             LC_MESSAGES=en_US.utf8
 [7] LC_PAPER=en_US.utf8       LC_NAME=C
 [9] LC_ADDRESS=C              LC_TELEPHONE=C
[11] LC_MEASUREMENT=en_US.utf8 LC_IDENTIFICATION=C

attached base packages:

[8] base

other attached packages:
[1] xtable_1.5-6    Hmisc_3.8-3     survival_2.36-5

Best,
