Hi All,
I want to know how to run an R file on my computer in R-Fiddle?
I tried source("filename.r"), but not working.
thanks,

run r script in r-fiddle
Hi Frank,
You could upload your R source file to a public URL, for example to
github and read via RCurl,
as source do not support https as far as I know. Here is a working example.
library('RCurl')
tmatrix <- getURL("https://raw.githubusercontent.com/msuzen/isingLenzMC/master/R/isingUtils.R")
eval(parse(text=tmatrix))
Not that you need to use raw URL for github file.
Best,
-m

heatmap.2 ordering & color key
...th the dendrogram I want
appearing at the top of the heatmap
If I use either of these orders the ordering works:
order <- c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24)
order2 <- c(24,23,22,21,20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2,1)
using the command:
heatmap.2(tmatrix, clusteredmatrixasdendrogram, col=bluered600,
dendrogram="column", scale="none", trace="none", Rowv=order)
however If I start mixing the numbers up e.g:
order3 <- c(1,4,7,10,2,5,8,11,3,6,9,12,13,16,19,22,14,17,20,23,15,18,21,24)
or
order4 <- c(24,21,18,15,23,20...

What exactly is an dgCMatrix-class. There are so many attributes.
...ily so I proceeded.
I find the TsparseMatrix indexing easier for my more naive notion of sparsity, although thinking about it now, I think I can see that the CsparseMatrix more closely resembles the "folded vector" design of dense R matrices. I will sometimes coerce CMatrix objeccts to TMatrix objects if I am working on the "inner" indices. I should probably stop doing that.
I sincerely hope my stumbling efforts have not caused any delays.

Thank you for your responses.
I guess I don't feel alone. I don't find the documentation go into any
detail.
I also find it surprising that,
> object.size(train$data)
1730904 bytes
> object.size(as.matrix(train$data))
6575016 bytes
the dgCMatrix actually takes less memory, though it *looks* like the
opposite.
Cheers!
