Hello All, I have a question about glm in R. I would like to fit a model with glm function, I have a vector y (size n) which is my response variable and I have matrix X which is by size (n*f) where f is the number of features or columns. I have about 80 features, and when I fit a model using the following formula,? glmfit = glm(y ~ x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10 + x11 + x12 + x13

I don't see the issue here. It would be helpful if people would report their sessionInfo() when reporting whether or not they see this issue. Mine is > sessionInfo() R version 3.4.3 (2017-11-30) Platform: x86_64-pc-linux-gnu (64-bit) Running under: Arch Linux Matrix products: default BLAS/LAPACK: /usr/lib/libopenblas_haswellp-r0.2.20.so locale: [1] LC_CTYPE=en_US.UTF-8

Hello, I have looked on https://www.r-project.org/bugs.html , but it seems that this is the only way to do it. The issue is that the precision used by write.csv is on consistant for big files. See the following code: First I create a large dataframe filled with random uniform values. Then I write it to .csv and print out the first and last lines. df = data.frame(replicate(100, runif(1000000,

My company supplies me with a very nice HP nc2400. Much faster, more memory, etc than my old HP nc4010. Problem is the drive is not swappable, and they encrypt the drive (the OS is XP). The nc2400 has a DVD/CDRW and 2 USB 2.0 ports so I was thinking..... Make a Live DVD with everything I need but map /etc /root /home and /var/log (and what else?) to a USB flash drive (16Gb are available

To my surprise, I can confirm on Windows 10 using R 3.4.3 . As tail is not recognized by Windows cmd, I replaced with: system('powershell -nologo "& "Get-Content -Path temp.csv -Tail 1') The last line shows only 7 digits after the decimal, whereas the first have 15 digits after the decimal. I agree with Dirk though, 1.6Gb csv files are not the best way to work with

Hi, I was wondering how it was possible to access the actual cluster exemplars from the APResult class. Currently it only spits it out onto the terminal if you type the object but there is no other way to see which one is the examplar. Would appreciate any help. Thanks, Sachin [[alternative HTML version deleted]]

If you want a character representation of a long formula (or a formula with long names), you can use: as.character(my.formula) However restriction on length of an as.character result returns only the beginning of a long formula, and without comment. In most cases, the following expression provides the complete result: paste(my.formula[[2]], " ~ ",

Hello everyone, I am trying to fit the following model All X. variables are continuous, while the conditions are categoricals. model <- lm(X2

The CentOS drive for the HP NC4010 is built. I just needed to use external instead of USB power for my USB CDrom. Go figure... I did this in my hotel room, where they only have wireless. I went down to the 'business center' and used an ethernet drop, but I don't think the registration worked. I didn't know that even for the ehternet drops you have to do that portal thing

My notebook has a habit of getting hot, and Centos just shuts down.

Hallo, All, I have a question about changing the height or scale of the y axis. When I use following two R codes, I can get two plots. Please look at the y axes, the number of indices (x1, x2, ?) on the y axis in the first plot is smaller than that in the second plot, and hence the space between any two indices in the first plot is wider than that in the second plot. As the number of indices

Have decided to give up on the embedded Broadcom 4312 wireless device in my son's Dell laptop. I get WEP open authentication to work, but nothing else. I was about to dump the bcm43xx kernel module and the bcm43xx-microcode5.fw firmware and work with the newer b43 module and associated firmware. However, he claims that at school, he has always had intermittent problems with wireless under

I am trying to get JPilot working. I have configed gnome-pilot-applet, but it is not talking to the USB connected Treo650. My Treo has my name as the user, so from the applet, I see also a userid (my UID on this system it seems). I try to put that on the Treo and nothing happens. I have enabled the Backup Conduit. I am using /dev/pilot, which shows up when my Treo is connected via its USB

Hi All, I have a query about time based sequences. I know such questions have been asked a lot on forums, but I couldnt find the exact thing that I was looking for. I want to create a time-based sequence which will mimic the trading window AND would span multiple days. Something like below: "2011-01-03 09:15:00 IST" "2011-01-03 09:15:01 IST" .... .... ....

This is a new Centos 5.1 install on a HP nc2400 (that use to run XP). Completely clean install; blew away the XP partitions...

I have a defective HP-Compaq nx9420 and so I am looking to replace it. I have pretty much decided to buy no further MicroSoft based products and would very much like to hear recommendations for a suitable notebook host to provide me with Linux based alternative. Given that all the basic functionality required is provided, the main thing that I am looking for is reliability of the host itself. I

Hi there and thanks in advance. I have a large symmetrical matrix stored in a text file. After load in R I would like to extract the same number of columns and rows (symmetrical submatrix) using their labels. I have tried this code in order to extract columns, but R console gives me the "+" sign at the end of the code, pointing out incomplete command, so it is not working:
