I reproduce from memory my exhaustive look into this issue. RODBC uses the Microsoft ODBC DLL's developed by Microsoft. These DLL's perform an automatic determination of column type based on the contents of the first N rows of cells in each column, where N [0,16]. N may be set in the Windows system registry, and there are a few other things that may be set in the system registry which

R-ers! Referees demand that the line in the KM-curve should be changed to dotted at the point where standarerror is <= 10 %. I don't think it's a good habit but I urgently need to implement such a thing in R with survfit, survplot or another program. They also want numbers at risk below the curve Some help, please....

Dear List I have run into some problems with boot.ci from package boot. When I try to obtain a confidence interval of type bca, boot.ci() returns the following error when the data set i large: Error in bca.ci(boot.out, conf, index[1L], L = L, t = t.o, t0 = t0.o, : estimated adjustment 'a' is NA Below is an example that produces the above mentioned error on my machine. library(boot)

Dear list, I have some help file for S-Plus 2000 in .d and .sgml format. Is there a way to translate these files to .Rd files to use in an R package? Thanks Fredrik Lundgren

Dear list, How should missing values be expressed in Excel before extraction to R via RODBC. I'm bewildered. Sometimes the representation with NA in Excel appears to work and shows up in R as <NA> but sometimes the use of NA in Excel changes the whole vector to NA's. Blank or nothing or NA as representation for missing values in Excel with dateformat gives NA's of the whole

Dear R-gurus, Where can I find a simple logistic regression model which can handle random effects as well among all the R-packages? With thansk in advance Fredrik Lundgren Norrk??ping, Sweden

Dear all, I've a problem with bootstarp package... I want to bootstrap correlation ratio of some data. my code is: f<-function(d) cov(d$x,d$y)/sqrt(var(x)*var(y)) boot(d,f,R) As a result I got an error: Error in statistic(data, original, ...) : unused argument(s) (.. .) d is a data.frame containing two vectors with labels x and y. Also, another thing I have problem

I like to bootstrap regression models, saving the entire set of bootstrapped regression coefficients for later use so that I can get confidence limits for a whole set of contrasts derived from the coefficients. I'm finding that ordinary bootstrap percentile confidence limits can provide poor coverage for odds ratios for binary logistic models with small N. So I'm exploring BCa confidence

Hello experienced R-ers, I'm converting from S-Plus Win 98SE to SuSE 8.1, R 1.62 and have run into som problems. 1) When I use help.start() netscape comes up OK and all links are accessible except "Search Engine & Keywords" : search doesn't work and the keywords from base doesn't respond either. ?command within R gets netscape running and works OK. 2) I haven't

Hello everybody, when I create an object of class boot with the function tsboot() from the package boot and try to compute several types of confidence intervals with boot.ci("object of class boot created with tsboot") I obtain the warning message, that "BCa-intervals are not defined for time-series bootstraps". Does that hold in general? Or is it just not defined in

Dear R'ers, I use R version 2.10.1 (2009-12-14) Copyright (C) 2009 The R Foundation for Statistical Computing ISBN 3-900051-07-0 and Mac OS X 10.5.8 and use to work in different dierectories. When doing so it appears as if the .Rhistory file from my home directory always is loaded even when I want the file from the directory where I'm working. I have tried to fix it through preferences

To Brian Ripley, Thanks! Yes indeed, It functions if you hit return at the prompt 1: but this had to be done for five times! Later five packages were found named NA with the description NA NA but all the rest of the 'libraries' are there in proper order with names and descriptions.

Hello, I'm not much of a programmer, and am trying to understand the workings of the function below called "RStatFctn" within this bootstrap procedure. RStatFctn is defined to have two arguments: "x", intended to be a data vector; and "d" intended to be an index (or so it looks to me). Later, "rnormdat" is created to be the data vector. However,

Hello, Much clearer now, thanks. It's a matter of changing the function boot calls to return the predicted values at the point of interess, education = 50, income = 75. I have changed the way the function uses the indices a bit, the result is the same, it's just the way I usually do it. pred.duncan.function <- function(data, indices) { mod <- lm(prestige ~ education +
