Hi R-helpers, Can some one tell me how to train 'mynn' of this type?: mynn <- nnet(y ~ x1 + ..+ x8, data = lgist, size = 2, rang = 0.1, decay = 5e-4, maxit = 200) I assume that this nn is untrained, and to train I have to split the original data into train:test data set, do leave-one-out refitting to refine the weights (please straighten this up if I was wrong). I just don't know

Hello everyone, this is a very simple question but I could not find the answer. :-( Is there any function in R for calculating the rank of a matrix? (In the sense of the dimension of the vectorial space that spans) Thank you in advance!

I?m new to R so maybe this issue has been asked before and I still could not read the complete set of past messages sent to the list. I found a weird behabiour that I will explain with a simple example. Lets consider the following block of commands: > x <- diag(c(1,4,10)) > x [,1] [,2] [,3] [1,] 1 0 0 [2,] 0 4 0 [3,] 0 0 10 > invx <- x^-1 > invx

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. I have been using SAS for some time, and now I have discovered R. I am very happy with it, but I have not found out how to perform some of the multiple comparisons I was used to do in SAS. With the SAS/STAT, I generally used the MEANS (for comparison of arithmetic means) and the LSMEANS (for adjusted means) statements of the GLM procedure (I

I am trying to install a custom plugin in my Rails app: script/plugin install http://git.eyequeue.net/plugins/mt_capistrano.git Instead of installing the plugin, I get the following error: shallow over http or ftp not supported Any ideas on how to fix this?

Let''s say I have: map.resources :teams do |team| team.resources :squads, :shallow => true end When I want to generate a form_for a squad, I need both the team and squad for new/create, but only the squad for edit. This means I need: edit: form_for(squad) new: form_for([team, squad]) This seems not very dry. Is there a more idiomatic way of doing this? Right now,

Hi, I'm trying to figure out how to link against symbols from the core com32 shallow module at runtime. I see references to _root_.c32 (EXEC_ROOT_NAME) in com32/lib/sys/module/exec.c, but can't find where this module is created in the build infrastructure, if indeed it is created at all. Does anyone have any pointers?

Hi all, I am using rsync to sync a directory tree of ~2 million files. I am using rsyncrypto with filename encryption to encrypt the files before syncing. When encrypting filenames, rsyncrypto assigned each file a filename which is made of hex digits. It also has the option to put the files in directories, where the location of the file is determined by the file's name and a parameter

Hi, It would be nice if there was a tool for checking the validity of any object. validObject() is of course the natural candidate for this but right now it doesn't work on S3 objects: df <- data.frame(aa=1:4, bb=letters[4:1]) attributes(df)$row.names <- c("A", "B", "C", "A") 'df' is an invalid data frame instance: > df

Hello, As this little program illustrates, duplicating a STRSXP does not seem deep enough. require( inline ) fx <- cfunction( signature( x = "character"), ' SEXP y = PROTECT( duplicate( x ) ); int n = LENGTH(x); int nc = 0 ; char* p = 0 ; for( int i=0; i<n; i++){ p = (char*)( CHAR( STRING_ELT( y , i ) ) ); nc = strlen( p ) ; for( int j=0; j<nc; j++){ p[j] =

I have a question about shallow copies in R. Since R 3.1.0, subsetting a dataframe with respect to its columns no longer result in deep copies. This is an amazing change in my opinion. Now, subsetting a data.frame by rows (or subsetting a matrix by columns or rows) still does deep copies. In particular, it is my understanding that running a command on a very large subset of rows (say

Hi, I wonder if anyone knows a study dealing with the minimum valid number of observations when using CART?. On top of that, when using RandomForest, is it possible to obtained a interpretable tree model as the graphical output of the analysis, just like in "rpart"?

Hello R users, I am trying to run a model with a binary response variable (nesting success: 0 failure, 1 success) and 8 fixed terms. Nesting success was examined in 72 cases in 34 territories (TER) during a 6 study years. Territories are nested within 14 patches (PATCH). I want to run a model taking into account these nested factors and repeated observation. To do this, I assume that the best

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. Sorry for sending this question twice, but I would really like to know your opinion on this topic. I have been reading about the (in)convenience of using least-squares means (a. k. a. adjusted means) in multiple comparisons (I used to resort to them when using SAS). I even read a post in this list warning against them, but not giving much detail.
