Re: [R] something missing in summary()
I will take advantage of this thread with a request of my own. Would it be possible to add an index in the result of str(df )? For large dfs I find myself counting for the position of certain variable(s) again and again (for indexing purposes).

I know these summary value can be obtained easy, but can't understand why these two pieces of information are not provided with the other info. I assume you mean summary.data.frame? Given a data frame, df, I would use str(df) before summary(df) because I want to see, for example, which columns are factors or ordered factors or ... That information is present in the value of summary(df) but in a more subtle way. As pointed out below the number of rows in the data frame is the total number of observations for each of the variables so putting that information in the summary for each variable is redundant. There has even been an appeal on this: http://tolstoy.newcastle.edu.au/R/help/06/02/20706.html However, I didn't find any petition you could sign (but I found many surprising petitions when googling on this). Perhaps somebody will set up a petition page some day. With time, I've learnt that if something obvious is missing in the base R, there is a reason. Probably the Core thinks that you shouldn't use sd in a summary, but it is a poor and misleading statistic (they neither have skewness and kurtosis). You may learn to live without sd if you survive over the first impact. I don't think this was an explicit decision by R-core. It was a case of S compatibility so the original decision was made at Bell Labs and that group was highly influenced by John Tukey who worked with them. I imagine that is why the summary of a numeric is a 'five-number' summary plus the mean. I would say the surprising and unconventional part of that summary is the fact that it includes the mean. On the other hand, there are things like R-squared and significance stars in summary.lm, which spoils the image of purity in the Core. However there is the option show.signif.stars which can be set to FALSE and which I always do. Number of observations may not be very useful in summary.data.frame, because it varies so little among variables. The R-help message cited above and its follow-ups suggest some ways of locally modifying the code and maintaining the modifications over the upgrades of R.

Re: [R] counties in different colours using map()
since dr. bivand seems to be away, i will try to help a little :-)
i did not work with the database that comes with maps, but with shapefiles from
http://www.census.gov/geo/www/cob/co2000.html#shp. you need to merge the
dataframe that you have with the shapefile.
do you have access to gis software? the merging can be done with r but it is
quite cumbersome.
The road to plot the map could be:
_
require(maptools)
a=read.shape(your_merged_file.shp, dbf.data=TRUE, verbose=TRUE)
attach(a)
win.graph(width=5,height=3, pointsize=8)
plot.Map(a, auxvar=the_variable_to_plot_from_dbf_file, xlab= , ylab= ,
ol=NA)

Subject: [R] counties in different colours using map()
Hi,
I would like to plot a map of US counties using different colors. map()
seems to be the function to use, e.g.
library(maps); map('usa'); map('county', 'colorado', add=T,fill = T,
col=c(1:5))
plots Colorado counties using colours 1 to 5.
However, I want each color to represent a certain value - a value to be
picked from a data frame.
This code should show a correspoding map at the level of states:
state.names - system('tr [A-Z] [a-z]', state.name)
map.states - unix('sed s/:.*//', map(names=T,plot=F))
state.to.map - match(map.states, state.names)
color- votes.repub[state.to.map, votes.year = 1900] / 100
map('state', fill=T, col=color); map('state', add=T)
It is copied from page 6 in
Richard A. Becker, and Allan R. Wilks, Maps in S, ATT Bell
Laboratories Statistics Research Report [93.2], 1993.
http://public.research.att.com/areas/stat/doc/93.2.ps
I also wonder whether the county names are available in the database
used by map(), and, if yes, how to extract or utilize them.
Thanks!

My problem comes from the last two #comment lines : #(if data row names do not match polygon IDs, will reorder, or fail if # any differ or absent The two data row names differ and some are absent, that's why I used merge (and posted on this list, not on r-sig-geo :-)).

Re: [R] Size of R user base
Why not ask those downloading rw1091 to complete (at their choice) a small survey (including questions such as 'will it be used by a group or an individual'). It would provide some data that could lead to an estimate as good as anything else.

I don't know, but it does seem to be quite widespread (at least for commercial software). so, why an Open Source software would not be able to monitor the number of users? That would make R into spyware, and there exist software to monitore and warn aganst/automatically remove spyware, and some users have such installed (and it will grow). Not quite spyware. Spyware generally works in more covert ways and tries to hide itself from the user. However, quite a few people think that having programs connecting to places on the internet without being asked is annoying and a potential invasion of privacy and it may even cost people money if they're on a dialup non-flat-fee connection. It is possible to ask: I mentioned pine, which does, and so do some perl installers. I don't think people would mind if the rw1091.exe installer had an option (ticked by default) to `call home', but I don't think we would learn enough for this to be worth setting up. -- Brian D.

Well, it's a matter of taste. However, both the topic and the target group would be totally different.
