I'm getting this error when I try to run the function MLearn(): Error: could not find function "MLearn" I have the MLInterface tools installed. But when I look for MLearn "??MLearn" but I don't find it. The closest thing I find is the method MLearn_new() under MLInterfaces. I've tried replacing MLearn() with MLearn_new() in my script, but I still get the same

Hi all, I ran a discriminant analysis with some data and want to get a general idea of prediction error rate. Some have suggested using X-fold cross validation procedure. Anyone know if there is a function for this in R? Thanks, Wade [[alternative HTML version deleted]]

Hello, I have been trying to install R on a Sun box running Solaris 2.6. I am running into a strange error when trying to make R. Basically, everything compiles fine, but it stops when trying to "make doc". Here's the output of the compiler: >Building system startup profile >You should `make docs' now ... >make: Fatal error: Don't know how to make target

I would like to selectively remove rows from a table. I had hoped that I could create a table and selectively add rows with something like > NewTable<-table(nrow=100, ncol=4) > NewTable[1,]<-OldTable[10,] but that doesn't work. The former call gives > NewTable ncol nrow 4 100 1 while the latter call gives a table the length of OldTable. Making a matrix, m, with the

Hi, Suppose I have the following data name     score Abel        88 Baker      54 Charlie    77 stored a  table called myData. I want to write a function that will create a table which is a subset of myData containing those have a score > 75.

Hi all, This should be easy, but I can't seem to figure it out. I have a table like this named newtable a1 a2 a3 a4 Cnts Score 1 1 0 0 4 3.28 1 0 1 1 2 2.63 I want the following: a1 a2 a3 a4 Cnts Score 1 1 0 0 4 3.28 1 1 0 0 4 3.28 1 1 0 0 4 3.28 1 1 0 0

Hi, i am unable to install the rugarch package. More than that i do not even find this package in my list of possible packages.

Ok, so I'm slowly figuring out what a factor is, and was able to follow the related thread about finding a mode by using constructs like my_mode = as.numeric(names(table(x))[which.max(table(x))]) Now, suppose I want to keep looking for other modes? For example, Rgames> sample(seq(1,10),50,replace=TRUE)->bag Rgames> bag [1] 2 8 8 10 7 3 2 9 8 3 8 9 6 6 10 10 7 1

I have recently upgraded to Ubuntu Gutsy and, for the first time, am using a 64-bit installation. After failing miserably to install R from source, not a problem for me in the past with a 32-bit install, I went the route of using the Debian Etch build. This went smoothly, but I am unable to update my numerous R and BioConductor packages, getting non-zero exit status errors on each package. Is

Is it possible to create a database in MySQL via RMySQL? Also, is the format for the authorization field 'userName/password at databasename'? I saw an example like this somewhere in the documenation, but I haven't found the actual specification. Thanks, Barnet Wagman

Here's my contribution to R. When R interacts with external programs (MySQL, cURL, etc.), it often requires a pasted string that is sent to these programs. For readability reasons, it is often preferable to have complex commands (SQL for example) spread on several lines. However, the normal paste function requires to add additional ' ", ' at the end of each line and another '

Dear R users, First of all sorry for this question, surely quite naive. (I searched on the R site but was unable to find by myself). I have a table, called infile : 1 2 3 4 5 6 7 8 9 I would like to read it and ignore the rows with 1st element > 3 I do it now with a for loop, and it's ok, but I was expecting something simpler, like : intable = read.table(infile); newtable =

Hello all, I''ve got a site that will be used by people (hopefully) all over the world. One of the requirements of registration is country and province of residence. I have a list of all the countries in the world and all their subnational entities. Currently, the two lists are divided between a pair of comma-delimited text files. If this were something less dynamic and cool, I''d

Dear all, I am still fairly new to R and try to analyze large tables of data generated from genomic experiment. Currently, I am trying to plot pair of experiments coming from different file, trying to look at the behavior of individual feature in pair of experiment. My problem is that I have independent list from different source and I would like to plot the pair of value using a common key. As
