[R] using latex() in R for Unix

[Paul Johnson]

This thread piqued my interest in how to use Hmisc latex() to produce
the tables that I actually want, rather than the ones that come out by
default.  Actually, I'd be glad to use R2HTML or any other tool if I
can make the output suit my taste.

 Here's a small working example that does not require any special libraries.


x <- rnorm(100)
y <- rnorm(100)
 mylm <- lm(y~x)
 Estimates <- cbind(coef(mylm), sqrt(diag(vcov(mylm))))
 colnames(Estimates) <- c("OLS estimate","std. error")
 rownames(Estimates) <- c("Intercept","Education")
 latex(Estimates,file="/home/pauljohn/test4.tex",digits=4)

That creates the top part of the table like I want it, except there
are no stars on the standard errors.

I want to add the diagnostic information, sample size, the R-square,
and root mean square error:

sumobj <- summary(mylm)
## tedious pasting alert:
sumStat <- paste("N=  ",sum(sumobj$df[-1]), ", R^2 =", 
sumobj$r.squared, ", RMSE = ", sumobj$sigma)

# The following does not have the desired effect because it creates
and appends a whole new table

latex(sumStat, file="/home/pauljohn/test4.tex", append=T)

How can I "snug up" sumStat right at the end of the table?
