Re: [R] subset data using a vector

Jim & Michael: I really appreciate your guidance in creating the function I wanted. I took suggestions from both of you and was able to complete this function. I had to split the process into two functions as listed below. I just thought to send the results to the list in case someone might

Re: [R] Ensure distribution of classes is the same as prior distribution in Cross Validation

Right now, using `method = "cv"` or `method = "repeatedcv"` does stratified sampling. Depending on what you mean by "ensure" and the nature of your outcome (categorical?), it probably already does. On Mon, Nov 23, 2015 at 7:04 PM, TJUN KIAT TEO wrote: > In the caret train

Re: [R] Plotting Example Fail

Thank you for your suggestions. I am quite grateful to understand that plotting is reliable and consistent in R. I had believed that this was based on a built-in dataset within the R programming language, just as the New Zealand volcano is. I look forward to further participation in R as I

Re: [R] Plotting Example Fail

But please spend some time with an R tutorial or two (An Intro to R ships with R; there are many more on the Web) before you post further here. Many such elementary confusions and time wasted -- both yours and ours -- will be avoided if you do so. Cheers, Bert Bert Gunter "Data is not

Hello, I am quite new to R and have high expectations for my future with it. R version 3.0.2 (2013-09-25) -- "Frisbee Sailing" Copyright (C) 2013 The R Foundation for Statistical Computing Platform: x86_64-pc-linux-gnu (64-bit) I have stepped back to an earlier tutorial and found an odd

Re: [R] Plotting Example Fail

rpois(100, 5) gives a different set of random numbers each time it is called, so if you want repeatable results compute it once and use its value in the calls to plot. E.g., r <- rpois(100, 5) plot(table(r), type="h", col="red", lwd=10, main="hello") Bill Dunlap TIBCO Software wdunlap

[R] Non-linear fit?

I need to fit a sinusoidal curve to x-y data that exhibits a sinusoidal pattern. The curve will be: y = a*sin(w*x +p) ; where I need to get the best fit choice for the parameters a, w, and p. Could anyone suggest which package and routine I should use? I have less than 1000 data

Wrong list (mostly). You would do much better at the Bioconductor list, https://support.bioconductor.org/ Cheers, Bert Bert Gunter "Data is not information. Information is not knowledge. And knowledge is certainly not wisdom." -- Clifford Stoll On Tue, Nov 24, 2015 at 9:04 AM, debra

Re: [R] Probing a protein sequence alignment in R

One way would be to use the biostrings and msa packages from bioconductor. Use AAStringSet() to collect your sequences, and (e.g.) msaMuscle() to align them. Then use BStringset() to extract the subrange you need, and e.g. table to look at the distributions... table(BStringSet(, start=50,

[R] Probing a protein sequence alignment in R

I have 15 protein sequences of 99 amino acids each. After doing some looking around I have found that there are several ways you can read sequences into R and do pairwise or multiple alignments. I, however, do not know how to probe changes at specific positions. For instance, I would like to
