similar to: Select Random Rows from a dataframe

Hello again R-folks, I'm trying to apply a loop to multiple data frames and then organize the data in a manageable form. I have the code for my loop figured out (thanks to help from this list)...it runs up to 2000 iterations of a "while" loop until it finds a 40-row "d2p" column sum >5 n<-nrow(dsub.f1) test<-0 for(k in 1:2001){ if(k>2000){ break} #stops

Hello R-universe... I am having trouble writing a function which contains a loop so I can sapply() it to a list of data frames Each data frame has 241 observations of 15 variables. My loop takes a random sample of one row until the 40 consecutive rows after the sample have a d2p(variable) sum greater than 5. here is my loop code (it works fine when applied to a 241 observation data frame):

Hi All, I'm running into a problem with GAM (in the MGCV package). When I try to estimate the model, I get the following error message: 1> fit <- gam(ndvi~s(rain)+s(temp)+s(rainl1)+s(rainl2)+s(rainxY)+s(rainl1xY)+s(rainl2xY)+s(tempxY), data=dsub, weights=wvec) Error in while (mean(ldxx/(ldxx + ldss)) > 0.4) { : missing value where TRUE/FALSE needed Using

Given a freshly produced quantreg.Rcheck directory, I was able to reproduce this crash by running R -d gdb # make

Hi- I want to fit a model with crossed random effects and heteroskedastic level-1 errors where inferences about fixed effects are of primary interest. The dimension of the random effects is making the model computationally prohibitive using lme() where I could model the heteroskedasticity with the "weights" argument. I am aware that the weights argument to lmer() cannot be used to

Gurus: I have a new version of my quantreg package with minimal changes, mainly to fix some obscure fortran problems. It fails R CMD check ?as-cran with the error: Running examples in ?quantreg-Ex.R? failed The error most likely occurred in: > base::assign(".ptime", proc.time(), pos = "CheckExEnv") > ### Name: plot.rqss > ### Title: Plot Method for rqss Objects

Hi David, What kind of "a lot of out-of-tree changes"? You should push changes incrementally as you do work. Holding onto changes means that many things, not just reformatting, can make them need to be redone. We frequently clean up and rewrite code to make it cleaner and easier to maintain. We are moving to a more strict internal review and pushing of changes and post commit

I tried switching to the USB version of bcmxcp_usb and get this error when I try starting up upsdrvctl or bcmxcp_usb like so: /etc/nut/bcmxcp_usb -DDDD -a powerware -u nut I used this for ups.conf: [powerware] driver = bcmxcp_usb port = auto With the serial/usb dongle, I used this successfully: [powerware] driver = bcmxcp port = /dev/ttyUSB0 What devices does

Can someone recommend a video card that's capable of driving a monitor at 2560x1600 or 2560x1440 and just works with Centos 7 without requiring any outside video drivers? I would prefer to stay with the built-in video drivers that are included with Centos 7 if possible; I don't play games and such, so I'm not looking for high performance 3D -- I just want a high resolution desktop.

Hi, I'm still hassling with the consultative/attended transfer stuff. Someone please help me identify this A lot has already been said about the ATA186. Some report it works fine, others say it doesn't. Lets get clarity on this. My scenario is reasonably simple (I think) Phone A: SIP/video1 Phone B: SIP/werkkamer Phone C: IAX2/provider Phone A calls phone B, they chat: *CLI> show

is there a utility or SOME method to determine which /dev/videoX (like /dev/video0 or /dev/video1) is being used by a device??? Example I have a USB camera and a USB TV module how do I determine which device is on /dev/video0 and which is on /dev/video1 I have seen perhaps a way in dmesg but I am looking for the BEST way and the correct way. Thanks, Jerry

Ralph, Conrad, Now that we have ROE as a means to describe a multi-track ogg file - i.e. a means to author Skeleton - I assume this is supposed to describe how we map ROE information into Skeleton through the use of fisbone message header fields, right? In this case I wonder if you have gone over all the current ROE spec and made sure that all this information is either in ROE or easily

Hi David, I agree with you that it would be rude to simply clang-format the MIPS backend without coordination with any out-of-tree derivatives. To be honest, it hadn't occurred to me that there would be any such derivatives and the possibility wasn't raised in our internal discussion before we brought the subject up on this list. I'm keen to coordinate with such derivatives to
