Hello all, I have not been able to find an answer to this problem. I feel like it might be so simple though that it might not get a response. Suppose I have a dataframe like the one I have copied below (minus the 'calib' column). I wish to create a column like calib where I am subtracting the 'Count' when 'stain' is 'none' from all other 'Count' data for

Hi, I was wondering if I might be able to ask some advice about doing residual plots for the lmer function in the lme4 package. Our group's aim is to find if the expression staining of a particular gene in a sample (or "core") is related to the pathology of the core. To do this, we used the lmer function to perform a logistic mixed model below. I apologise in advance for the lack of subscripts. logit P(yij=1) = â0 + Ui + â1Patholij where Ui~N(0, óu2), i inde...

Hello, i've ubuntu 8.04 (32bit) with wine 1.0-rc5. I've installed without problem vampire: bloodlines and it works fine in the menu, but when the game starts the audio works well but the video is all "orange". As graphic card i've a ati moblitiy x1600 with official driver (installed using envyNG) and before start the game i've used compiz-switch to disable compiz. the

I've experienced some troubles using scp with remote files with spaces, amphersands or parantheses in their filenames on Linux hosts. This happens: stain at false:~$ scp "bender.linpro.no:blapp blapp" . scp: blapp: No such file or directory scp: blapp: No such file or directory stain at false:~$ scp "bender.linpro.no:blapp&blapp" . bash: blapp: command

Dear colleagues, I have a problem which has bitten me occasionally. I often need to prepare graphs for many variables in a data set, but seldom for all. or for any large number of sequential or sequentially named variables. Often I need several graphs for different subsets of the dataset for a given variable. I run into similar problems with other needs besides graphing. What I would like to

Hi, As part of the analysis of a longitudinal study, I have a list, called wg, on R 1.3.1 for windows created as follows - wg <- by(xx, xx$mrn, function(xx) lm(xx$maternal.wt ~ xx$gestation, data=xx)) xx is a data.frame, and so wg contains the results of 293 linear regressions, as lm objects. Now what I want is to extract the 293 intercepts and regression coefficients as a vector, and

Hi, I think I'm missing something very obvious, but I am missing it, so I would be very grateful for help. I'm using rpart to analyse data on skull base morphology, essentially predicting sex from one or several skull base measurements. The sex of the people whose skulls are being studied is known, and lives as a factor (M,F) in the data. I want to get back predictions of gender, and

Hi, I would be grateful for help with a problem which is irritating me. I am quite sure that I am doing something stupid, but I can't see what it is. I am running R 1.7 on Windows 2000. The graphics device is the PC screen. The graphics from the nlme demonstration in Bates an Pinheiro's manual work just as advertised. The CO2 data and the Orthodont data dsiplay

Hi, I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way. I had a look on biops and EBImage (Bioconductor) but they are not automatic... Did you already use/know a such package ? Thanks, - Martial _________________________________________________________________ Tchattez en direct en en vidéo avec vos amis !

Hi, I'm analysing some anthropometric data on fifty odd skull bases. We know the gender of each skull, and we are trying to develop a predictor to identify the sex of unknown skulls. Rpart with cross-validation produces two models - one of which predicts gender for Males well, and Females poorly, and the other does the opposite (Females well, and Males poorly). In both cases the error

Hi, I have a valid SPSS .sav file (which I can open happily in SPSS v11 on Windows XP). Opening it in R2.41 on Linux we get this message :- > HSE3023 <- read.spss("HSE.sav") Error in read.spss("HSE.sav") : error reading system-file header In addition: Warning message: HSE.sav: Variable X234 indicates variable label of invalid length 256 Now variable X234 has indeed a

Dear colleagues, This may be a question with a really obvious answer, but I can't find it. I have access to a large file with real medical record identifiers (mixed strings of characters and numbers) in it. These represent medical events for many thousands of people. It's important to be able to link events for the same people. It's much more important that the real record numbers

Dear R-experts, I imported successful a workspace from Matlab. The information is stored in the variable data. If I use the command "length(data)" I get back a number which corresponds to the number of variables which were imported. Here it is 82. Now I only want to know the names of the imported variables to modify my program. Can anyone help me? My knowledge which I tested yet to

Dear colleagues, I would be very grateful for your help with the following. I have banged my head off this question several times in the past, and repeatedly over the last week. I have looked in the usual places and found no obvious solution. I fear that this just means I didn't recognize it, but I'd be very grateful for your help. I am scoring 8000 psychometric tests - the SCQ, if

Hi, This code is trying to produce a series of graphics files, with plots of male and female disease rates by age, one plot per disease. The dataframe contains a variable 'Age' and a set of variables called 'Male_CVD, Female_CVD,Male_RTA,Female_RTA, and so on. For each disease, I want to pull out the column of data containing the word 'Male' and plot this against age, and then

Hi, I've a question about the qplot. I use facets=Antibiotics~Gram.Stainng to draw 6 plots in a panel. Now the problem is within each 'Gram.Staining' categorical level there are some antibiotics does not have value (in my case is log(MIU)). Because some antibiotics are positive gram staining and some are negative. So my question is how to remove these missing value rows in the plot? My code is qplot(Bacteria,log(MIC),data=project2,fa...

I apologize overturned the sentence, rewrite it properly!

Hi, I would be very grateful for advice on getting confidence intervals for the ordinary (non smoothed) parameter estimates from a gam. Motivation I am studying hospital outcomes in a large data set. The outcomes of interest to me are all binary variables. The one in the example here, Dead30d, is death within 30 days of admission. Sexf is gender (M or F), Age is age in years at the start
