Hi. I've done a standard barplotexample using R1-8.0, redhat8, probably using a GhostScript-integration. How can I improve the "sharpness" of the fonts. See for example the barplot (originally jpg coming from R) which is part of this screendump: http://www.zug.dk/Members/Nielssteenkrogh/1067525916309553166/element_103003161029 I'm not sure where to improve the this.

We are constructing growth charts (age/weight and age/length) for children with diagnosis that impacts weight/length. But we we don't know how to use R for producing growth charts. We are collection data of Age, Weight and Length. The data are used to produce diagnosis-specific Growth charts (like the CDC Growth Charts:

I'm using R on a linux redhat 8.0 installation. The special danish characters (ÅØÆæøå) are showed wrong on the screen.

Hi. I'm going to introduce the R-package for a group of medical doctors later this week and is a little confused about there use of a test named "willcoxon-pratt" for testing if the clinical and biochemical markers has decreased significantly after the use of some drugs for a group of patients. Looking into the R-functions I would in R recommand using a matched-pairs Wilcoxon

Dear R-list. I'm doing af logistic analyses using gml.

This question relates to the use of the RODBC package for retrieving data from a MS Access database. It is quite easy to retrieve data sitting in tables but is it possible to select from views based on these tables? The archives do not touch on this point. sqlTables() lets me see tables and views but only the tables yield data. Do I need to recreate these views on the R side of the connection?

I am running R 2.01 on Mac OS 10.3.7. Whenever I save graphs, they are saved as PDF files. Are there any other file formats to which I could save my graphs. I would like to directly export my graphs to MS Word, if possible. Thank you in advance.
