Dear list members,
again a stupid question: I wish to plot the results of hierarchical
clustering
with dendrograms and with heatmaps. I used the following functions:
heatmap(exprs(data)[selected,])
and
plot(hclust(dist(t(exprs(data)[selected,]), method = "euclidean"),
method =
"average"))
The different arrays belong to different classes and I would like to
label these
classes by colours - e.g. class 1 as blue, class 2 as red and class 3
as green.
I have an expression set data and a target vector like this
> targets$vivo
[1] "h" "l" "h" "n" "h" "n" "0" "n" "h" "0" "h" "h" "h" "h" "h" "h"
"h" "0" "h"
[20] "h" "l" "l" "n" "h" "h" "h" "h" "n" "h" "0" "0" "h" "l" "h" "h"
"h" "n" "h"
[39] "h" "h" "h" "h" "l" "l" "h" "l" "0" "h" "h" "n" "h" "l" "0" "l"
"h" "l" "l"
[58] "n" "h" "0" "h" "0" "n" "0" "h" "0" "h" "h" "h" "h" "n" "n" "h"
"n" "h" "l"
[77] "l" "n"
It would be great to label the celfile names by colors indicating the
classes
"h", "l", "n" and "0".
Is this possible in BioC?
Thanks again in advance and kind regards,
Heike
