I am using the Principal Component Regression function (pcr) and it seems to want it this way > datap3.pcr <- pcr(water ~ X, 10, data = datap3, Validation ="cv") Error in model.frame.default(formula = water ~ X, data = datap3) : invalid type (list) for

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

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.

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

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" .... .... ....

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,

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.

My apologies for not including sessionInfo(), and I'm a bit angry at myself for that. Retrying in a fresh session of R, I get different results. More specifically, I get the expected result where accuracy is the same in the first and the last line. As I didn't include my sessionInfo() in my previous mail, I can't figure out why I now have a different result. So I'm positive

Colleagues, I am using R to assemble RTF documents (which are plain text). I need to embed a JPEG graphic that was created with R. I presume that the steps need to be: a. read the file into R b. convert the object to HEX format c. write the converted object to a textfile. If I read the file into R using readLines, I get the following (only the first 5 lines shown): > >

What OS are you on? On Ubuntu 17.10 with R 3.4.3 all seems well (see below for your example, I just added a setwd()). [ That said, I long held a (apparently minority) view that csv is for all intends and purposes a less-than-ideal format. If you have that much data, you do generally not want to serialize it back and forth as that is slow, and may drop precision. The rds format is great for R

Dear all, I have encountered a weird behaviour in R survival package which seems to me to be a bug. The weird behaviour happens when I am using 100 variables in the ridge function when calling coxph with following formula Surv(time = futime, event = fustat, type = "right") ~ ridge(X1, X2, X3, X4, X5, X6, X7, X8, X9, X10, X11, X12, X13, X14, X15, X16, X17, X18, X19, X20, X21, X22,

See description in the attached patch. -------------- next part -------------- This quick hack adds primitive support of UTF-8 as a server 'character set' to Samba 2.0.7. All file, share and user names are stored on server in UTF-8, and translated into client code page (not UCS2) on the fly. Additionally, server string conversion is added. Tested with Chinese and Russian Windows clients.
