Hi, here are three results of random forest (version 4.0-1). The results seem to be more or less the same which is strange because I changed the classwt. I hoped that for example classwt=c(0.45,0.1,0.45) would result in fewer cases classified as class 2. Did I understand something wrong? Christian x1rf <- randomForest(x=as.data.frame(mfilters[cvtrain,]),

Dear R users I am currently investigating time series analysis using an irregular time series. Our study is looking at vegetation change in areas of alien vegetation growth after clearing events. The irregular time series is sourced from Landsat ETM+ data, over a six year period I have 38 scenes. For certain periods I have monthly data while for others, images are up to three months apart. So far

Full_Name: Henrik Bengtsson Version: 1.5.1 OS: WinMe Submission from: (NULL) (217.210.0.243) In the Perl script $R_HOME/bin/check there is a bug under the section "Check R code for syntax errors" where the 'Rfiles <- c(...)' is build up. If there are too many files in @Rfiles the source code line generated will be too long and weird things will happen, e.g. strange

hello everyone we are developing a package that has worked up until R3.0 which we just tested. the issue is as above .... when we call a function that works in R 2.15.2 from R 3.0 we get an error Error in .Call("antsImageRead", filename, pixeltype, dimension) : "antsImageRead" not resolved from current namespace (ANTsR) this Error occurs when the .Call is made from

Hello, I?m using zero-inflated Poisson regression via the zeroinfl() function to analyze data on seed-set of plants, but for some reason, I don?t seem to be getting the output for all three levels of my two categorical predictors. More about my data and model: My response variable is the number of viable seeds (AVInt), and my two categorical predictors are elevation (Elev) and Treatment

Dear useRs, Please find the new package mFilter version 0.1-2 on CRAN. The package implements several time series filters useful for smoothing and extracting trend and cyclical components of a time series. The routines are commonly used in economics and finance, however they should also be interest to other areas. Currently, Christiano-Fitzgerald, Baxter-King, Hodrick-Prescott, Butterworth, and

Hi all, If I use a moving average, it will smooth the choppy time series, but it will lead to lagging... How do I smooth timeseries without the lagging effect? Thanks!

Hi everyone, I am trying to fit a sine function on one year of wind data. I have two questions below. Looking around on the net I managed to get the following: Sine Equation: y = a + b * sin( c + d*x ) b is the amplitude, c is the phase shift, d is something deal with periodicty of data*.* This can be linearised by sin( c+dx ) = cos(c) * sin(dx) + sin(c) * cos(dx). If one calls dx = x1 y

HI I use glm in R to do logistic regression. and treat both response and predictor as factor In my first try: ******************************************************************************* Call: glm(formula = as.factor(diagnostic) ~ as.factor(7161521) + as.factor(2281517), family = binomial()) Deviance Residuals: Min 1Q Median 3Q Max -1.5370 -1.0431 -0.9416 1.3065 1.4331 Coefficients:

I''ve encountered a small problem--some of the documents in my Documents and Categories window are not opening, while others are. Have others experienced this issue? If so, do you know how I might fix it? The coded segments of text are still there when I open up the categories with which documents have been tagged, but I can''t seem to pull up the whole text of some of these

Hi Weft QDA 1.0.1''s available now. It''s a bug-fix and maintenance release, and a recommended upgrade for existing users. What''s new: - fix for crash when moving categories using the Category Tree - fixed a bug on Win 98 and Win ME that made Weft a ''non-starter'' - avoid crashes with over-large and malformed text documents - fix a text scrolling bug on

Hola a todos, Me gustaria saber como puedo evaluar / obtener el resultado guardado en un objeto cuando este se ejecuta. Quiero decir, el resultado de la siguiente expresion: > paste("res_UP_sep_dec_","16_17_18",sep="") [1] "res_UP_sep_dec_16_17_18" es un objeto (una lista) cuyo nombre es precisamente res_UP_sep_dec_16_17_18 >

Hi listers, Does anybody knows if the function qda for quadratic discriminant analysis provides the coefficients of quadratic discriminants... Well, I find out that for the linear discriminant analysis lda, the fonction provides the coefficients... Thanks in advance, Marcio -- View this message in context: http://www.nabble.com/Quadratic-Discriminant-Analysis-%28qda%29-tp22747647p22747647.html

Dear R Help Members, I am aware how to plot the LD1 vs LD2 from a lda in R, using the code: plot(baseline.systat.hat$x, col=baseline.systat.hat$class,pch=as.numeric(baseline.systat.hat$class)) However, I need to use the quadratic discriminant function, qda due to data properties. Is there a way to obtain the same sort of plot for from a qda object (and the output of predict qda). I have not

Hi, my name is Leandro and im Argentinian. I plan to build a web CMS on ruby on rails, to provide CAQDAS functionality, and since im building the site in Ruby on Rails and open source, i want to know if Weft QDA engine is open source. If so, id would come in handy to be able to reuse/improve an existing ruby based CAQDAS. I''d like to emphasize the fact that i dont mean to profit from it,

z <- qda(train, cl) save(z, file = "qda.dat") load("qda.dat") predict(qda.dat, test)$class I'm trying to save z where z <-qda(train, cl) and load z for later use in predict(z, test)$class. I think I successfully saved z by save(z, file = "qda.dat") but when I tried to load by load("qda.dat") and call predict(qda.dat, test)$class, it gives me error

I?m having trouble with my Weft project. Some of my categories no longer open when I click on them. Any ideas as to why this is happening? Also, for some reason two of my imported documents no longer open when I click on them. The content is there when I click on my categories but I can?t open the document to add new coding. Thanks!
