[R] Sweave trim output

[Dimitris Rizopoulos]

Dear All,

I'd like to trim the output produced in a Sweave code chunk. For 
instance, in

fit <- lm(conc ~ . - Plant, data = CO2)
summary(fit)

I'd like, skip the info after the coefficients' table, and possibly 
replace it with '...'.

I've created this small function to do this, which is based on 
capture.output():

trim.output <- function (x, lines, above = FALSE) {
     if (above)
         cat("\n...\n\n")
     cat(paste(x[lines], collapse = "\n"))
     cat("\n\n...\n")
}

out <- capture.output(summary(fit))
trim.output(out, 1:13)


but I was wondering if there is an *official* way to do this.


Thanks in advance.

Best,
Dimitris
