I am outputting some graphs from SpatStat using a for loop. I want the png
files to include the i and j from the nested loops in their names. For
example, I want the file names to look like "i-j_plot.png". The code is
below:
ma <- levels(marks(X))
n <- length(ma)
for(i in 1:n)
for(j in 1:n)
{
png(filename=????)
plot(envelope(X, Kcross, i=ma[i], j=ma[j]))
dev.off()
}
