similar to: detecting null values in a CSV file

Hello, I realize that using: x[x > 3 & x < 5] I can fetch all elements between 3 and 5. However I read in from a CSV file, and I would like to fetch all columns from within a range ( 842-2411). In teh past, I have done this to fetch just select few columns: data <- read.csv(filein, header=TRUE, nrows=320, skip=nskip) data_filter <- data[c(2,12,17)]

Hello all, I have a very large file (280k lines) containing three comma separated variables. The first variable is a 0 or 1 depicting a pass or fail. The other two are X and Y coordinates. Is there a good way I can represent this data in a chart/plot form other than using a 3d histogram? If I need to use the histogram, should I base my chart off the example contained in the RGL package? Thanks a

I am attempting to perform some simple data manipulation on a large data set. I have a snippet of the whole data set, and my small snippet is 2GB in CSV. Is there a way I can read my csv, select a few columns, and write it to an output file in real time? This is what I do right now to a small test file: data <- read.csv('data.csv', header = FALSE) data_filter <- data[c(1,3,4)]

Hello, Is there a simple way to take an input, and convert the decimal integers to binary? In this case, I have a CSV file, and I need to convert the first column of every line to binary. Thanks. -- Jason Thibodeau [[alternative HTML version deleted]]

Plus I would like to let you know that it works like a charm. Snort can now see those packets. -----Original Message----- From: shorewall-users-bounces@lists.shorewall.net [mailto:shorewall-users-bounces@lists.shorewall.net] On Behalf Of Thibodeau, Jamie L.

I have started looking at implementing shorewall as a bridge and had a few minor questions. First off if I want to define hosts in the hosts file would it be #ZONE HOST(S) OPTIONS Trust br0:eth0:xxx.xxx.xxx.xx net br0:eth0 loc br0:eth1 #LAST LINE -- ADD YOUR ENTRIES BEFORE THIS LINE -- DO NOT REMOVE Or like #ZONE HOST(S)

Does anyone know what a good maximum number of machines I should place in the ProxyArp list? Thanks Jamie

The following examples are confusing to me. It is OK, to assigned NULL to one element in a list. The result is still a list. However, a list of NULL's are reduced to NULL. I don't understand how this conversion occurs. Could somebody let me know what is going on? > X=matrix(1:8, nr=4) > apply(X,1, function(x) {if(x[[1]]==3){NULL}else{x[[1]]}}) [[1]] [1] 1 [[2]] [1] 2 [[3]] NULL

Has anyone successfully setup a shorewall Ucarp solution?

I was messing around with R and I found an example R behaving oddly: a <- alist(NULL, "bob", c(3,6,2,3)) a a == 'NULL' a == "NULL" a == 'cat' If I create a list with a NULL value >a <- alist(NULL, "bob", c(3,6,2,3)) >a [[1]] NULL [[2]] [1] "bob" [[3]] c(3, 6, 2, 3) and run some tests on 'a', the '==

Clients: Some sites just show the top area not the full page. Some sites cant be reached at all. I think it 90% may be the MTU/MSS problem. But I already have set the shorewall.conf CLAMPMSS=1400 or CLAMPMSS=Yes, but it doest make things good. I would be mad. Anybody helps me would so appreciated! If you want know more info. to diag my problem, I would be please to.

If I''m using proxyarp and I try to ping that host from a machine in the net(untrusted) zone should I get a reply from the firewall address saying Destination host unreachable? I would like it to just time out. Jamie

I'm trying to use sqdf's function read.csv.sql to read CSV files in which the missing values are represented by NA's. Plain old read.csv works fine on these files, but they are rather large and I'd like to filter using sql-like statements. However, even if I specify field.types correctly and nrows=-1, it still turns the columns with NA's into chars or 0. I'm trying to make

I made an atempt to run snort_inline and shorewall on the same system but I could not get snort to see the packets. Maybe someone with a little more iptables knowledge could tell me what I''m doing wrong or if its possible to have the systems setup so that it places packets that the firewall would allow into QUEUE. After setting up and starting shorewall I then issue the following

I'm looking for a way to figure out which accounts have not been logged in to in over n days. It occurs to me that, perhaps, the way to do this would be to look at the mtime on one of the dovecot-maintained files, like 'dovecot-uidlist'. Is there a particular file that would be modified on (almost) every login, whether it be via POP or IMAP? -Ben -- Ben Beuchler
