Bug in "SOM" package in R.
 
This simple code withot for loop runs:-------simple.r--------
 
library(som)
A <- as.matrix(read.table("C:/code/h.txt", sep="\t", header=TRUE,
row.names=1))
print(som(A,1,2)$visual)
print(som(A,1,3)$visual)
----------------------------------------
 
The same code if inserted in for loop generates "Assertion failure" in
Rgui.exe.
 
This is Microsoft Visual C++ runtime error in Rgui.exe and File =
tn/vec.h
 
Line 250 
Expression: i<=n_
 
Code with for loop:----------------------------sim.r--------------------
 
library(som)
A <- as.matrix(read.table("C:/code/h.txt", sep="\t", header=TRUE,
row.names=1))
for(x in 2:3){
print(som(A,1,x)$visual)
}

Please send bugs in packages (I think this is som, not SOM, and R does
care) to the package maintainer (Cc:ed here), as the FAQ asks. Also,
please give the version of R and of the package used.

I can't test this as I cannot even install som with gcc 3.4.0, and I have
just reported that to the maintainer.

As the package maintainer has no access to R-bugs and basic information is 
missing I am going to close this report on R-bugs and refer it to the 
maintainer.
