Hello,
I would like to write in a variable the following string :
Hello World
If I do cat(Hello ,\World\), I have the good result on the screen
but it can not be affected to a variable. If I do the same thing with
paste paste(Hello ,\World\) it does not work since \ seems to be

Hi
I am using the heatmap function in package mva to look at large
correlation matrices visually.
Is there any way to flip the output of heatmap plot left-right so
that, if presented with a correlation matrix, it plots the unity
elements in the correlation matrix along a diagonal from top left to
Philippe
You seem to have the right answer already, unless I misunderstand...
If I define:
x = Hello \World\
Then the default print method for this character string will give the rather ugly
looking:
x
[1] Hello \World\
But this is just R telling us that it does recognise the escape

The paste is doing the right thing -- it is how it is displayed
that matters:
jj - paste(hello, \world\)
jj
[1] hello \world\
cat(jj)
hello world print(jj, quote=FALSE)
[1] hello world

My feeling is that heatmap is not the right thing to use on a correlation
matrix. The heatmap function expects a data matrix, and does a two-way
clustering of cases and variables. It tries to rearrange the rows and
columns so that similar colors are closer together. This obviously will not

It's clear (even to me ;-) that the idea of reordering columns

I am really new into R, and I would like to know if it is possible to load a

I would apreciate any help,
