[R] x labels out of Quartz canvas

2008-06-16 Thread MeMooMeM

Hi R world, 

I am such a newbie, with only 4-5 days of R experience. I did a search in
forum history but couldn't find a solution to my problem... Sorry if it's
obvious:

I managed to draw a barplot (yey!) with xlabels of 'long' names (filenames,
to be particular). To make them readable, I place them perpendicular to the
axis (las=2). When I do that, however, these names don't fit inside the
Quartz window and they are truncated. 

Is there a way to change the Quartz window size after plotting (or, as an
alternative, to scale the plot down so it fits in there) ?

Thanks a lot!

PS: This is the very first of my zillion of questions!

Re: [R] x labels out of Quartz canvas

2008-06-17 Thread MeMooMeM

Thanks a lot!

I looked at the document. It shows how to set the size of the canvas, but
not how to change it *after* plotting. Now I start with a bigger canvas, but
the plot is scaled into it, so I am having the same problem again :( 

I keep on reading tough. Thanks a lot for your help!

[R] Row and Col length of a matrix?

2008-06-17 Thread MeMooMeM

Hi, 

Is there a direct command to get the row and col length of a matrix? 

My ugly solution is: length(mtx[,1]) and length(bcf[1,])

Thanks!

[R] color2D.matplot axis names

2008-06-17 Thread MeMooMeM

Hi,

I finally came up with a nice colored matrixplot, using the color2D.matplot
function of the plotrix package. But I can't assign xtics and ytics to this
plot. I made sure that the matrix has correct colnames() and rownames().

Here's what I do:

a=matrix(1:16, 4, 4)
colnames(a) <- c("X1", "X2", "X3", X4)
rownames(a) <- c("Y1", "Y2", "Y3", "Y4")
color2D.matplot(a,c(0,1),c(0,0),c(0,0),show.legend=TRUE, show.values=TRUE)

As you can see from the output of these commands, the ticks are numbers, but
not the names.

Thank you so much in advance!

Re: [R] x labels out of Quartz canvas

2008-06-18 Thread MeMooMeM

Dr. Ripley, I appreciate all your help. The graph looks great now. Just in
case someone searches for a similar problem:

>You need to set the *margins* not the size of the canvas.  See par's mai 
>and mar and the figures in that document.

Here's how I do that:

par(mar=c(7,7,7,7))
color2D.matplot(abs(cors),extremes=c("blue", "red"),show.legend=TRUE,
show.values=TRUE, axes=FALSE, xlab="", ylab="")
