R crashing
Hello,
This is what I am trying to do: I wrote a little function that takes
addresses (coordinates) as input, and returns the road distance between
every two points using Google Maps. Catch is, there are 2000 addresses, so I
have to get around 2x10^6 addresses. On my first go, this is what I did:
#########################################
getRoadDist = function(X,complete=F){ # X must be a matrix or data frame
of coordinates; lat and lon
require(RCurl)
Y = apply( X, 1, function(x){ paste(x[1], ",", x[2], sep=""...

Why would you "guess" that? Given your magnitudes, I suspect it's a
scaling issue. Try centering and scaling your Baci variable before
fitting.

From NUM to INT
...I`m getting the following error for the 'Baci' variable:
'Error: (maxstephalfit) PIRLS step-halvings failed to reduce deviance in
pwrssUpdate'. I guess this message is because the baci variable is not a
an integer, and cannot be transformed into an integer as R has a threshold
of
2x10^9 even in 64 bit R.
It runs fine for the fungii variable.
If you guys want to run the data (attached), the full command is below.
Thanks.

Stacking matrix columns
I wish to stack columns of a matrix into one column. The following
matrix command does it. Any other ways? Thanks.
> x<-matrix(1:20,5,4)
> x
???? [,1] [,2] [,3] [,4]
[1,]??? 1??? 6?? 11?? 16
[2,]??? 2??? 7?? 12?? 17
[3,]??? 3??? 8?? 13?? 18
[4,]??? 4??? 9?? 14?? 19
[5,]??? 5?? 10?? 15?? 20
> matrix(x,ncol=1)
????? [,1]
?[1,]??? 1
?[2,]??? 2
?[3,]??? 3
?[4,]??? 4
?[5,]??? 5

Recommendations for QoS, PoE Switches
Hi all,
For a top quality setup, I will need to install high quality VoIP switches
with QoS and PoE. My potential customer should not have any problem with
call quality. Experienced folks, Please advice me what switches to install
and at what price. I may need it for upto 100 phones. What else should I
consider so that phones work without problem along with the computers on the
same network?

From NUM to INT
Can you explain why you need them as 'integer', A floating point
representation can hold a value upto ~4.5e15 as an "integer" keeping the
precision that you might need.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

From NUM to INT
Dear all:
I converted the columns (Baci, Meti, Fungii, Protozoai) into integers
(using excel) and then imported the data (.txt) into R. Interestingly, the
other three variables were loaded as INT, but the 'Baci' one continued as
Num.
I imported the data using the following command line:
X <- read.delim(file.choose(),
header = TRUE,
dec =

How to protect your code? Obfuscater?
I just made a rails application that I plan to sell and dsitribute. I
want to distribute it without having to worry about someone stealing the
code and selling their own version. How do I do this? Is there a ruby
obfuscator or anything that can keep someone from seeing the code?
Thanks for your help.
