Hi, Could you please tell me whether SVM can do multiple regression or not? Cheers, Amy _________________________________________________________________ Browse profiles for FREE! Meet local singles online. [[alternative HTML version deleted]]

Hi Could you please explain the line that I got from the documentation of R? does it mean that there is a difference between using and not using the formula interface with SVM ?: If the predictor variables include factors, the formula interface must be used to get a correct model matrix.

Hi, I understand from help pages that in order to use a data set with svm, I have to divide it into two files: one for the dataset without the class label and the other file contains the class label as the following code:- library(e1071) x<- read.delim("mydataset_except-class-label.txt") y<- read.delim("mydataset_class-labell.txt") model <- svm(x, y, cross=5)

hi, could you please tell me what kind of cross validation that SVM of e1071 uses? Cheers, Amy _________________________________________________________________ View photos of singles in your area! Looking for a hot date? [[alternative HTML version deleted]]

Hi, Could you please tell me how I correct the following error message? “Error in object$tables[[v]] : subscript out of bounds” This is the code: library(e1071) data(iris) attach(iris) class_label <- names(iris)[1] myformula <- formula(paste(class_label,"~ .")) mymodel<-naiveBayes(myformula, iris,cross=3) predict(mymodel,iris) ##Error in object$tables[[v]] :

Hi, Could you please tell me whether there is a difference in the result of svm when using formula instead of class label? Cheers, Amy _________________________________________________________________ Browse profiles for FREE! Meet local singles online. [[alternative HTML version deleted]]

All, our dovecot installation provides a bundle of intermedia CA certificates using the ssl_ca option. 2.3.0 does not supply the bundle, resulting in various clients either complaining about an unverifiable server cert, or quietly not connecting. The log has Jan 5 17:01:46 Bounce dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=XXX, lip=YYY, TLS

Dear everyone, Your code is slow and you are interested in performance optimization for scientific software? Figuring out where’s the bottlenecks guided by performance evaluation tools. If you are interested in porting your code to a HPC hardware platform and architecture, than OpenACC as a user-driven directive-based performance-portable parallel programming model might be a solution. What are

Hi! More than a week ago I sent the below-mentioned message but did not receive any answer. I think that the subject heading was not correct, and so I changed it. Hope that I will get an answer now.

Hi, I am using the plot function to make a simple plot of my data with one variable against another and want to colour the data points according to a third variable. The third variable is continuous (Time) and I want to try two different ways of colouring the data points, either: Divide time it into three groups and then colour each data point accordingly eg. 30-60 minutes in green,

Hi, is there a way to color the branches or text label of the branches of dendrograms e.g. from hclust() according to a grouping variable. Here I have something in mind like: http://www.sigmaaldrich.com/content/dam/sigma-aldrich/life-science/biowire/biowire-fall-2010/proteome-figure-1.Par.0001.Image.gif (ectodermal, endodermal, mesodermal). /johannes

Hi everyone, I'm having problems with plotting my data. I have a set of positions with different attributes and I'm wondering if I can plot it, as x,y plot, with gradient colours according to a 3rd factor. Is it possible to show gradient segments between postions and not one-coloured segment between each one? I've been trying plotrix color.scale.lines with no luck. I'm very

Hi, I am trying to plot several columns in different graphs in columns and rows. The first column of my data file is the time, and the third is the 'elevation angle' with 19 different numbers. I would like to plot the rest of the columns with the x axis as time and the individual angles in different colours. Here is the code I am using right now. It plots the different columns with time,

Dear all, I'd like to get a percentage variable based on a group, but without creating a new data frame. For example: data(iris) iris$percent <-unlist(tapply(iris$Sepal.Length,iris$Species,function(x) x/sum(x, na.rm=TRUE))) This does not work, I should have only three standard values, respectively for setosa, versicolor, and virginica. How can I do this? MANY THANKS, Karine

Hi, I have date and time in a format like this: " 2007-02-21 05:19:00". Do you which function i can use to derterminate the difference in time between this value and an other one. For exemple: this one : 2007-02-21 05:19:00 and this one : 2007-02-20 14:21:53 Thanks a lot, Karine H. _________________________________________________________________

hi, I have my data time expressed in character string exple "5:20" (hour:min) and i want to convert these in times recognized by R. I have tried the POSIXct function: balise07$Hour <- as.POSXIct(balise07$Hour) but it didn't work. Do you know why? Do you know how i can convert my string character in a real time? Thanks Karine HEERAH Master 2 mention

Dear R colleagues, I am trying to plot some geophysical data as a filled contour on a continent map and so far the guidance from the R-help archives has been invaluable. The only bit that still eludes me is the colour key (legend) coming with filled.contour: I prefer to generate my own colour palette, mainly based on the quantiles of tenths of the data in order to capture the whole range (of

Hi everybody. i have 2 datasets : one with a long grid a lat grid and a bathymetry grid the second one only has the long and lat coordinates. So i want to know the bathymetry associated to the second dataset. I thought it was a good idea to do an interpolation between the two datasets. I find a script doing that on matlab but i want to do it on R. Do you how to do it? for ii =
