I have the data frame... df <- cbind(expand.grid(d=as.factor(c(2,5)), n=c(100, 200), beta=as.factor(c(0.2, 0.8)), group=LETTERS[1:2]), value=runif(16))
... which I would like to display in a table like ... require(tables) tabular(d * beta ~ group * mean * Heading() * value, data=df) Now I would like to insert (vertical) space between every other line of the table. I checked the manual and vignette of 'tables', but it only covers the case when there is just one variable specified in the left-hand side of the formula (so "to the left" of "~"). I tried to adapt the idea of using RowFactor() ... tabular(RowFactor(1:4, "", spacing=2, space=0.5) + d * beta ~ group * mean * Heading() * value, data=df) ... but obtain ... Error in `colnames<-`(`*tmp*`, value = "") : length of 'dimnames' [2] not equal to array extent Cheers, Marius ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
