attempted merge() returns: cannot coerce type 'closure' to vector of type 'any'
...idea why i cant use merge() in the normal way here? I'm forced to
add the column using:
temp.b <- cbind(x, y[match(rownames(x), rownames(y)),17])
All insights appreciated for this leaRner,
cheers,
Karl

I have some experience using the rgl package to create 3D PCA plots, but
have no idea where to start for an image like this.
I'd really appreciate suggestions & help on how might achieve this using R,

How does one start R within Emacs/ESS with root privileges?
...s as good as its purported to be. So
maybe my motivation is nonsensical to expereinced ESS/R users. If so i'd
really appreciate tips on efficient package installation/maintenance
using Emacs/ESS.
TIA,

Both failed.
#** And while i've got your attention- is there a 'letter equivalent' to
seq() which would have worked nicely for prfxs? ie., letter.seq(A:F)
Thoughts and suggestions sincerely appreciated,

How to remove all objects except a few specified objects?
How to remove all R objects in the RAM except for a few specified ones?
rm(list=ls()) removes all R objects in the R work space.
Another question is that whether removing all R objects actually releases
the RAM? Thanks.

Venn Diagram corresponding to size in R
I was wondering if anyone could help me figure out how to make a Venn
diagram in R where the circles are scaled to the size of each dataset. I
have looked at the information for venn (in gplots) and vennDiagram (in
limma) and I cannot seem to figure out what parameter to change. I have
looked this up online and do not seem to be seeing anyone else who has
posted this question or the answer to it

using the design matrix to correctly configure contrasts
...ically, the contrasts i can NOT work out are:
t1.S.CvsAll.Times & t1.L.CvsAll.Times
ie., similar to t1.S.RvsAll.Times & t1.S.RvsAll.Times above but for the
"C" tissue, not the "S".
