Hi, is there a test for the H0 skewness=0 (or with skewness as test statistic and normality as H0) implemented in R? Thank you, Christian *********************************************************************** Christian Hennig Fachbereich Mathematik-SPST/ZMS, Universitaet Hamburg hennig at math.uni-hamburg.de...

Hi, I have run rpart to construct a regression tree. Is there any simple method to draw a nice picture of it, as it is usually done in books and paper to visualize the tree? Thank you, Christian *********************************************************************** Christian Hennig...

Hi there, are there any R-packages for computations required in sampling theury (such as confidence intervals under random, stratified, cluster sampling; I'd be partoculary interested in confidence intervals for the population variance, which is difficult enough to find...

Hi, I am plotting a matrix/data frame with 10 variables by pairs. Is it possible to add another 10-dimensional point afterwards by something like points does for two-dimensional plots?

Hi there, two questions. 1) Is there any possibility to look up the help pages within R for more complex combinations of character strings, for example "Bayesian" AND "regression" but not necessarily "Bayesian regression"? 2) Is there a package/command...

Hi, is there a command for plotting two (or more) histograms in the same graph, or is there a low-level plotting command for adding a second histogram (in different color) to the graph of the first one? Best, Christian...

Hi, is there any function to fit a spatial CAR model or to compute the iterated Papadakis method as in Sec. 5.2/5.3 of Ripley (1981) Spatial Statistics? errorsarlm in spdep seems to be the SAR fit, or...

Hi there, is there any R-function for k-nearest neighbour agglomerative hierarchical clustering? By this I mean standard agglomerative hierarchical clustering as in hclust or agnes, but with the k-nearest neighbour distance between clusters used on the higher...

Addendum to: Error with library(mclust): library(ctest) works fine as well as library(MASS) and library(KernSmooth).

Hi list, is there any direct way to obtain confidence intervals for the regression slope from lm, predict.lm or the like? (If not, is there any reason? This is also missing in some other statistics softwares, and I thought...

Hi, is there any method for goodness of fit testing of an (as general as possible) univariate distribution with parameters estimated, for normal, exponential, gamma distributions, say (e.g. the corrected p-values for the Kolmogorov-Smirnov or Chi-squared...

Dear list, R CMD check on my updated package now generated the following error: "LaTeX errors when creating DVI version. This typically indicates Rd problems." But the Rd files (and everything else) were checked as "OK" (I removed the problem...

Hi, I would like to use the format function to get numbers all with three digits to the right of the decimal point, even in cases where there is no significant digit left. For example, I would like to get...

Hi there, I just updated my R to 3.0.2 and ran R CMD check --as-cran on the just produced new version of fpc. I got an error Error: package "MASS" was built before R 3.0.0...

Hi, this is to announce a new version (1.1-2) of my package fpc. Apart from the stuff already present in the older version (methods for fixed point clustering and clusterwise regression, somewhat bug-cleaned and with faster examples...
