Yes -- using textplot() from the gplots package. Cut & paste from its
example:

     ### 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))

So textplot(capture.output(summary(xlm)) may become be your new best friend.

Hth, Dirk
