Hi Readers, I have a question. I have a large dataset and want to throw away columns that have the same value in the column itself and I want to know which column this was. For example > x<-data.frame(id=c(1,2,3), snp1=c("A","G", "G"),snp2=c("G","G","G"),snp3=c("G","G","A"))

Hi all, A simple question which I don???t seem to be able to solve: I want to make a data.frame of 360 rows and 94228 column with only zero???s without having to type all these zero???s ;-) What is the easiest method?

Hi all, I want to make extra columns in my datafile where the id of every groupmember is mentioned in separate columns. To explain it better see the example: id<-c(1,2,3,4,5,6,7,8,9,10,11,12) group<-c(1,1,1,1,2,2,3,3,3,3,3,3) a<-as.data.frame(cbind(id,group)) a id group 1 1 1 2 2 1 3 3 1 4 4 1 5 5

Hi, I have a large dataset on which I would like to do the following: x<-data.frame(id=c(1,2,3), snp1=c("AA","GG", "AG"),snp2=c("GG","AG","GG"),snp3=c("GG","AG","AA")) > x id snp1 snp2 snp3 1 1 AA GG GG 2 2 GG AG AG 3 3 AG GG AA And then

Hi, I am trying to split multiple columns. One column works just fine, but I want to do it for multiple columns??? Example > a ID V2 V3 V4 V5 V6 V7 V8 V9 V10 1 PBBA0644 -- GG AA -- AA -- AA GG GG 2 PBBA1010 -- GG AA -- AA -- AA GG GG 3 0127ATPR -- GG AA -- AA -- AA GG GG 4 0128EHAB -- GG AA -- AG -- AA AG GG 5 PBBA0829 -- GG AA -- AA -- AA GG AG

Hi R-ers, I am struggling with my x-axis in a association plot. What I would like is to place the labels of the x-axis between the tick markers and normally the labels are printed at the place where the tick marker is placed. I don???t want to move the tick marker (it gives the switch between one chromosome and the next) but I just want to put the chromosome number in between the

Hello, I am relatively new to R, and I am trying to select the last observation within a group, where the group is defined by two variables. One of the variables is a date. In the below example, C3 varies within C2, which varies within C1. I need to select the last observation in C3 for 4 groups (C1*C2): 1x, 1y, 2x, and 2y. In my real dataset, C2 is a date (mm/dd/yy) C1 C2 C3 1 x 1 1

Hi, Apologies if this is a duplicate - been having mail server issues and I don't think I managed to send it when I tried this morning. It seems there is no .conf syntax highlighting script available for gedit. I'm thinking of putting one together myself, but don't want to reinvent the wheel. So I'm just enquiring if anyone knows of one that already exists that i've missed.

Hello, I'm currently using a tool that provides a Loess fitting, but I obtained results that are slightly different from those provided by R implementation of the Loess. That's why I would like to know if you could give me a source (bibliography or web) that explains in a clear way each step of the algorithm, with the possible options to choose, etc.. in order for me to understand those

Hi, I have installed Asterisk 1.8 and am using realtime dialplan contexts from a mysql table. Asterisk keeps segfaulting. When I trace the thread ids associated with the segfaults in the full log, all they have in common is netsock2.c: == Using SIP RTP CoS mark 5 which is probably a red herring since it appears so often in threads that do not segfault. When compiling, I ticked all the

Hi, I am using netem to add loss and then adding another qdisc within netem according to the wiki. Then i want to change the netem drop probability without having to delete the qdisc and recreate it. I try it but I get invalid argument: thorium-ini hedpe # tc qdisc add dev ath0 root handle 1:0 netem drop 1% thorium-ini hedpe # tc qdisc add dev ath0 parent 1:1 handle 10: xcp capacity 54Mbit

Hello everyone, I recently bought a Riello IPG 600 UPS ( http://www.riello-ups.com/products/1-ups/39-iplug) to prevent hardware damage to my server in case of power outages (already lost two hard drives because of this) and I managed to successfully configure it with NUT version 2.7.4 available for Ubuntu 17.04: nut/zesty-updates,zesty-updates,now 2.7.4-5ubuntu2.1 all [installed]

Hello! It's a shoot in the dark, but I'll try. If one has a total of 100 (e.g., %), and three components of the total, e.g., mytotal=data.frame(x=50,y=30,z=20), - one could build a pie chart with 3 sectors representing x, y, and z according to their proportions in the total. I am wondering if it's possible to build something very similar, but not on a circle but in a square - such that

Dear All, I would like to to group the Ticker by Industry and create file names from the Industry Factor and export to a txt file. I have tried the folowing ind=finvizAllexETF$Industry ind is then "Aluminum" "Business Services" "Regional Airlines" ind2=gsub(" " ,"",ind) ind3 [1] "Aluminum"

Hi, I would have thought that when spawning a channel using the Originate() dialplan command, variables prefixed with two underscores would be preserved. However this does not work in the following case. Dialplan code: [intern] exten => 200,1,Set(__myvar="foo") exten => 200,n,Originate(Local/123 at test_orig,exten,dummy) [test_orig] exten => 123,1,NoOp(${myvar}) exten =>

Hi, I've just installed a binary version of Samba 2.0.3 on SCO 5.0.5 and am having some problems. I'm basically following "SAMS Teach yourself Samba in 24 hrs" book. On a Win98 machine I can see the SCO machine in the Network Neighborhood. When I try to connect it asks for a passwd and says that the passwd is incorrect when I enter it. It also displays

In lattice, using the command trellis.par.get for superpose.symbol, plot, symbol and/or dot.symbol shows that we can specify alpha, cex, col, fill (for superpose.symbol and plot.symbol), font, and pch. Trial and error shows that the font affects letters but not pch=1 or pch=3 (open circles and plus signs.) I want to use open circles and plus signs, keep the colors and cex I've specified but

Hi there! I am working a lot with VoIP in my company, so I thought to use linux bridge functionality together with tc to emulate delay, jitter, packet loss, duplication, reordering etc. for testing purposes in our lab against our VoIP products. I just recognized, that a basic bridge just with it''s minumum configuration of 2 network interfaces creates latency of approx. 5ms on very low

Hi, Greg, Eddie, I found that in SR-IOV + HVM environment, ping latency depends on ping interval. The NIC is Intel 82576 (1000Mbps), server uses xen-4.0.1, domain-0 is kernel-2.6.32 and HVM is kernel-2.6.31. The server and client are connected through a 1000Mbps switch. The data is as following: # ping -i 1 192.168.0.21 PING 192.168.0.21 (192.168.0.21) 56(84) bytes of data. 64 bytes from
