Create a PDF table

r

Solution

Yes there is as you can place text into graphs and hence into pdf devices.

The nicest wrapper for this may be the `textplot()` function in Greg Warnes' trusted gplots package. Below is the beginning of the examples section of its help page:

# show R version information
textplot(version)
# show the alphabet as a single string
textplot( paste(letters[1:26], collapse=" ") )

# show the alphabet as a matrix 
textplot( matrix(letters[1:26], ncol=2))

### Make a nice 4 way display with two plots and two text summaries 
data(iris)  
par(mfrow=c(2,2))   
plot( Sepal.Length ~ Species, data=iris, border="blue", col="cyan",   
      main="Boxplot of Sepal Length by Species" )    
plotmeans(Sepal.Length ~ Species, data=iris, barwidth=2, connect=FALSE,
          main="Means and 95\% Confidence Intervals\nof Sepal Length by Species")

info <- sapply(split(iris$Sepal.Length, iris$Species),
               function(x) round(c(Mean=mean(x), SD=sd(x), N=gdata::nobs(x)),2))

textplot( info, valign="top"  )
title("Sepal Length by Species")

reg <- lm( Sepal.Length ~ Species, data=iris )
textplot( capture.output(summary(reg)), valign="top")
title("Regression of Sepal Length by Species")

par(mfrow=c(1,1))

Problem

Is there a way to produce a PDF of a table from R in the same way you produce a plot (ie with pdf() or ggsave())? I realize there are ways with other programs (using sweave etc.), but I would like to produce it just from R.
