Dear list, I want the 1st, 2nd, 5th, and 6th columns of mtcars. After copying them, the columns become numeric class rather than data frame. But, when I copy rows, they data frame retains its class. Why is this? I don't see why copying rows vs columns is so different. > class(mtcars) [1] "data.frame" > head(mtcars) mpg cyl disp hp drat wt qsec vs

Fisher is not the only person that it may be necessary to read 4 or 5 times. The same may be the case for side comments that Bill Venables is wont to make. Now to the parallel universe that I have in mind. I wonder whether the time is opportune for a list that focuses on "Statistical Methodology for R Users". The difference from other statistical methodology lists is that it will be

Hi all, Since the vault for 7.3.1611 has been cleared out last sunday (20170207) - why is that? - I'm using git to download a "SRPM", or more accurately, its contents. However, using git has one major drawback: It is missing checksums for the files. Are there any plans to provide checksums for the files in git so I can be sure that what I download is actually not tampered with?

Came across a strange problem, I have a software raid1 with LV sitting on top. When I try to mirror an existing LV to a new LV with the tar command I get these error messages. mount /dev/vg00/base.centos /mnt/orig mount /dev/vg00/test /mnt/new cd /mnt/orig tar cf - ./|(cd /mnt/new; tar xf - ) ... File shrank by 406815 bytes; padding with zeros ... Read error at byte 49152, reading 10240 bytes:

Some time ago I mentioned the online version of the book "Numerical Recipes in C" http://www.ulib.org/webRoot/Books/Numerical_Recipes/ and inadvertantly stirred up a hornets' nest. I obtained from this book code to calculate the Incomplete beta function. It appears in: 6.4 Incomplete Beta Function, Student?s Distribution, F-Distribution, Cumulative Binomial Distribution, p.226, and it calls the log-gamma function that appears in: 6.1 Gamma, Beta, and Related Funct...

Dear all, What is the quickest and most efficient way to diff two data frames, so as to obtain a vector of indices (or logical) for rows/columns that differ in the two data frames? For example, > Xe <- head(mtcars) > Xf <- head(mtcars) > Xf[2:4,3:5] <- 55 > all.equal(Xe, Xf) [1] "Component 3: Mean relative difference: 0.6863118" [2] "Component 4: Mean relative

This reverts commit c7070619f3408d9a0dffbed9149e6f00479cf43b. This has been shown to regress on some ARM systems: by forcing on DMA API usage for ARM systems, we have inadvertently kicked open a hornets' nest in terms of cache-coherency. Namely that unless the virtio device is explicitly described as capable of coherent DMA by firmware, the DMA APIs on ARM and other DT-based platforms will assume it is non-coherent. This turns out to cause a big problem for the likes of QEMU and kvmtool, which...

Dear all; I need to run heatmap. Because my first column in my data is alphanumeric, I can not run as.matrix(scale(my_data)). So I need to make my data readable as in data(mtcars). In *mtcars *data the first column is alphanumeric and has no name. Thanks, Greg [[alternative HTML version deleted]]

Hi all, I know I'm probably stirring up a hornet's nest with this question/comment but I've spent the last few days working on a PHP-based class for the manager interface as we're preparing for a pretty big upgrade at our call center and I'm revamping all of the management apps I've written. I can connect to the manager interface and send query strings back and forth all

Dear R-help This is a follow-up to my previous post here: http://groups.google.com/group/r-help-archive/browse_thread/thread/d9b6f87ce06a9fb7/e9be30a4688f239c?lnk=gst&q=dobomode#e9be30a4688f239c I am working on developing an open-source automated system for running batch-regressions on very large datasets. In my previous post, I posed the question of obtaining VIF's from the output of

I seem to have unwittingly stirred up a hornets' nest here, so let me have one more say and leave it. Firstly, congratulations to Renaud Launcelot, who seems to have a better feel for wryness and irony in English than some of my native speaker colleagues. Of course R A Fisher is a seminal writer, indeed close to the founder of modern stati...

I have a rather basic question. How can I get R to generate a ANOVA table and a f-value for a hypothesis test such as: Data: group1 values: 5.2 4.5 6.0 6.1 6.7 5.8 group2 values: 6.5 8.0 6.1 7.5 5.9 5.6 ... H0: mean1 = mean2 = mean3 = mean4 HA: at least two means different where I want to evaluate using a f test statistic? F = MSTr/MSE I'd like a table similar to one that
