Hello R-help   I am working with large data table that have the occasional label,  a particular time point in an experiment. E.g: "Time (min)", "R1 R1", "R2 R1", "R3 R1", "R4 R1" .909, 1.117, 1.225, 1.048, 1.258 3.942, 1.113, 1.230, 1.049, 1.262 3.976, 1.105, 1.226, 1.051, 1.259 4.009, 1.114, 1.231, 1.053, 1.259 4.042, 1.107, 1.230, 1.048, 1.262

Dear useRs, I am trying to build my package (nonpareff) which deals with some models of data envelopment analysis. The building worked well, but checking complains when it tests examples. Zipped nonparaeff.Rcheck is attached. Following is the log. --------------------------------------------- arecibo:tmp arecibo$ R CMD build nonparaeff/ * checking for file 'nonparaeff/DESCRIPTION' ...

Running freeBSD 6.1 After changing chkrootkit to the latest version V. 0.47 and compiling it then running it I get the following: ==================<SNIPPIT>================ Searching for anomalies in shell history files... nothing found Checking `asp'... not infected Checking `bindshell'... INFECTED (PORTS: 6667) Checking `lkm'... You have 131 process hidden for readdir

How can I be sure if it is LKM or not? Today I've run chkrootkit and it gave me: Checking `lkm'... You have 179 process hidden for readdir command You have 179 process hidden for ps command chkproc: Warning: Possible LKM Trojan installed Checking `chkutmp'...

Hi all again, I must add, there are no log entries after June 9, 2004. "LKM" message first apeared June 8, 2004, after this day, there is nothing in /var/messages, /var/security ..... How could I look for suspicious LKM module ? How could I find it, if the machine is hacked and I can not believe "ls", "find" etc. commands ? Peter Rosa

Hello, last night, my chkrootkit crontab returned an alarm message : > Checking `lkm'... You have 1 process hidden for readdir command > You have 2 process hidden for ps command > Warning: Possible LKM Trojan installed Some research on google make me think it's probably a false positive. I tried few things : re-launching chkrootkit : "Checking `lkm'...

I am not sure if I had a compromise but I am not sure I wanted some other input. I noticed in this in my daily security run output: pc1 setuid diffs: 19c19 < 365635 -rwsr-xr-x 1 root wheel 204232 Sep 27 21:23:19 2003 /usr/X11R6/bin/xscreensaver --- > 365781 -rwsr-xr-x 1 root wheel 205320 Dec 4 07:55:59 2003 /usr/X11R6/bin/xscreensaver It was the only file listed and I didn't

Hi, I have a 4.9-STABLE FreeBSD box apparently hacked! Yesterday I ran chkrootkit-0.41 and I don't like some of the outputs. Those are: chfn ... INFECTED chsh ... INFECTED date ... INFECTED ls ... INFECTED ps ... INFECTED But all the rest is NOT PROMISC, NOT INFECTED, NOTHING FOUND, NOTHING DELETED, or NOTHING DETECTED. I know by the FreeBSD-Security archives that

Hello everyone, I want to get a 1km by lkm grid raster image using my csv data. If I call latitude=a, longitude=b and preciptation=c. a<-(1,2,3,4,5) b<-(6,7,8,9,10) c<-(10,20, 30,40, 50) Then I found an example in r help which goes like pts = read.table("file.csv",......) library(sp) library(rgdal) proj4string(pts)=CRS("+init=epsg:4326") # set it to lat-long pts =

Ok, I've googled for 15+ minutes, and have yet to find a usable answer, so I'm going to annoy everyone and ask here. I have, in my posession, a creative VoIP blaster. I have installed the fobbit LKM and I can see the device. Can I use it with asterisk in any meaningful way, shape, or form? I'd love to be able to buy an IP phone, ATA, or FXO card, but lack the funds at the moment

Dear UseRs, I would like to know the way to create a new column by naming it simultaneously. For example, in for() loop I want to create columns named as paste("test", i, sep = ""), as shown below. ---------------------------- dt <- data.frame(a = c(1, 2, 3), b = c(3, 2, 2), c = c(1, 3, 5)) for(i in 1:2){ dt$as.name(paste("test", i, sep = ""))

Hi useRs! I would like to know how to make aggregated data.frame with aggregate() tabulated. For example, I run the following command to aggregate re with respect to group1 and group2. > (aggr <- with(final, aggregate(re, group1, group2, mean))) Group.1 Group.2 x 1 1992 15 0.16392 2 1993 15 0.15467 3 1994 15 0.15456 4 1995 15 0.15391

I am inquiring on the list if anybody knows if the latest plus kernel includes the fixes for MD RAID-1 where it didn't pass down the BIO_RW_SYNC flag on cloned bios. This bug was discovered in December by the DRBD project and patches were posted by Lars Ellenberg from that project to the LKM which were then merged into the 2.6.19 kernel. The bug causes severe performance penalties for

PREFERED WAY OF DOING IT I have a data set of observations every second for a month long period, I want to extract the observations according to the date & time of another data frame ( the other data frame is in the same format). I want to do this to match these observations to my test observations (in the other data frame) which are done every 6 minutes. So basically im shrinking the

Dear UserRs, I draw filled contour plot with filled.contour function. By default, colors of filled.contour is terrain.colors which alters from green (the lowest level) to white (the highest level). I want the colors to alter from white (the lowest level) to green (the highest level). How can I set this color levels? Thanks in advance.

Dear UseRs, I would like to know the way to find classes of each column of data.frame().
