I have a suggestion for the posting guide. One problem with some posts is that they do not provide an example that can be reproduced. I think that many people just do not know how to easily specify some data and some technical assistance should be provided in the posting guide. If the problem depends on specific data they should be made aware, in the posting guide, of:
dput(x) since that outputs object x as R code which can then be easily copied from the post and pasted into a session. If its not dependent on particular data they can generate patterned or random data IF THEY KNOW HOW but many might find it easier to just use one of the included datasets so some guidance should be provided on the contents of a few of them, e.g. R comes with built in data sets. data() will list them, data(iris) will attach data set iris and ?iris, str(iris), summary(iris), head(iris) and dput(iris) will give more information on iris (after attaching it). The following are a few of the datasets that come with R: iris - data frame with 4 numeric columns and one 3 level factor nhtemp - a ts class time series faithful - data frame with two numeric columns warpbreaks - data with a numeric column, a 2-level factor & a 3-level factor Also letters, LETTERS, month.abb and month.name are built in character vectors that do not require a data statement to access. ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
