practical to loop over 2million rows?
New to R and having issues with loops. I am aware that I should use
vectorization whenever possible and use the apply functions, however,
sometimes a loop seems necessary.
I have a data set of 2 million rows and have tried run a couple of loops of
varying complexity to test efficiency. If I do a very simple loop such as
add every item in a column I get an answer quickly.
If I use a nested ifelse

Problem with filled.contour/image
Quick question - I am having problems creating an orographic image
(similar to volcano example). I have created a map matrix with 3 columns

lat.grid<-sort(unique(map$lat)
map.matrix<-matrix(map$height,nrow=length(lat.grid),byrow=TRUE)
The problem is when I type the filled.contour
command I get the...

auth client limit versus service count of mail processes

}

# Max. number of POP3 processes (connections)
process_limit = 2048
# Reduce spawns from hell
service_count = 100
}

The above works fine, no warnings.
Since 2 of our mailbox servers get a high number (2million/day) of IMAP
logins and resulting mail process spawns, I pondered doing the service
count bit for IMAP as well.
But adding a "service_count = 100" line (any value larger than 1 really) to
the imap section we get the dreaded:
