the following code apprantely, for some grand old reason, induces a syntax error: if (seq[i] = "A") m <- trans[1,] where seq is a vector and trans is a matrix. I cannot for the life of me see why this is wrong. Syntax error is: Error: syntax error in "if (seq[i] =" Sincerely, Norman Goodacre ---------------------------------

Dear mailing group, This is my first time here. Glad to have this resource! I am currently trying to load an Excel file into R (limma package loaded) using the source(*name of directory*) command, but it cannot open the file. I renamed the file as .R and .RData, to no avail. The Excel data contains one gene name per row and about 100 data points per gene (columns). I am only used to

Dear help group, Just fyi a markov chain is a sequence of transitions between states (say A,T,G,C - on a gene) with a given probability for each transition. In this case there'd be 16 different kinds, each with a different weight. Given a transition matrix (4x4) filled with all transition probabilities of course, how can I generate a random sequence of a given length, say 200?

Dear R mailing group, The second parameter for the function optim()is a function whose parameters are to be optimized. The description of this function given in the help file is the following: fn: A function to be minimized (or maximized), with first argument the vector of parameters over which minimization is to take place. It should return a scalar result.

Dear mailing group, I have loaded an Excel file into R by calling it ".csv" and using the "read.csv" function in R. However then I want to use the (limma package specific, I believe) function "hclust", which clusters data in a tree dendrogram, by similarity. However, I receive the errors msg.s: 1) "missing observations in cov/cor" 2) "In

Hi! I'm trying to install package Bhat on a Win machine, had a problem and figured out a fix, but would like to report the problem and make sure the fix is correct. This is what I do: 1. Download Bhat_0.9-07.tar.gz 2. Uncompress it and compress it back to Bhat_0.9-07.zip 3. Install from the R windows gui (that apparentely requires the zip compression and cannot deal with the tar.gz) But

Dear R mailing group, I am having extreme - and mysterious - trouble installing R. I tried simply dl ing R-2.3.1.tar.gz, and unzipping it, but after doing so, nowhere could I find a file called R-2.3.1.exe. I did however find an R-2.3.1.exe.manifest. I therefore tried the command line installation command - given in R-admin.pdf. This command is: tar zxvf R-2.3.1.tgz This is strange

I have two columns and I want to count hwo many pairs I have of the same element. For example. If I have a = c(1,2,3,4,5) b= c(12, 1, 34, 2, 5, 0, 10, 100, 11) It should return 3 (since 1, 2 and 5 occur in both columns). Columns need not be of the same length. -- Thanks, Jim.

wine has evolved too much in the recent years. and with the evolution new features have come. but unfortunately a program that tries to emulate a vast and complex system as windows are,has come to a point which it has flooded with bugs and "temp code". So the code freeze is a refreshing point which allows the programmers - contributors to polish their code so it can take more

Hi to all, I found in the R-help archive how to calculate the p-value for a gee result: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/74150.html but there are two questions (I am afraid they are basic questions ...) 1. why is the result multiplicated with 2 2. how could I decide between lower.tail =TRUE and FALSE: example:

Here are a few suggestions, wondering what others thought: When you generate a model for a DB table, it would be nice if the model.rb contained the DB schema (kind of like # commented out schema) right in the model file. This would make reference WAY easier and put all of the DB stuff in one easy file. Thanks. also nice, of course, woudl be for rails to try and ''guess'' the

so... I've got some mailman lists running on centos 6. apparently c6 has mailman 2.1.12, which is far too old to have the dmarc patches (introduced in 2.1.16 and updated in 2.1.??, so of course, I'm having ongoing issues with yahoo/sbc/att/aol/etc subscribers and bouncing messages ending up causing 30%+ of my subscribers not to be able to get mail. These are mostly non-technical

The setup is a samba server with mixed clients (samba clients and windows clients). The problem, I want the linux client to mount there home to their home share on the server.

Hi all, In response to Rodrigo Rosas''s message about mb_chars.upcase not giving the expected result on 1.9, I''ve done some work in a fork to make String#mb_chars always return an instance of a proxy class, both with Ruby 1.8 and Ruby 1.9. The end result of the patch is (hopefully) to make Rails'' multibyte functionality behave the same way in 1.8.7 and 1.9.x.

My system is 7.2.1511. When I run "yum update", it wants to install about 900 packages total. Most are labeled just "el7". A few "el7_1" and a lot are "el7_3" or 7.3. None are 7.2. I'm not surprised when I see 50-100 packages needing an update. But 900? And none specific to the installed system? My last update, of 4 packages, was Dec 31, 2016. I
