Re: [R] how to include bar values in a barplot?

As an original poster (and a brand new user of R), I would like to comment on the educational experience I have just received. ;) The discussion was interesting and enlightening, and gives some good ideas about the ways (tables, graphs, graphs with numbers etc.) to get the data accross to the ones one is presenting to. I see some of you guys do feel quite strongly about it, which is fine for me. I do not. I usually care for barplot aesthetics and informativeness more than for visual simplicity. That may change in time :) I see R graphical capabilities are huge but hard to access at times - that is when spreadsheet seems preferrable. For example, as a user of Linux I still cannot figure out why the fonts (and graphics in general) look much more ugly on R in Linux than they do in R on Windows - no smoothing, sub-pixell hinting, anything like that. That is what my next free time homework on R will be about :) Sincerely Donatas Glodenis PhD candidate Department of Sociology of the Faculty of Philosophy Vilnius University Lithuania __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

If the values are not real numbers, and have a lot of digits after the dot, the graph might become unreadable... see this vals <- c(1,1.1236886,4.77554676,5.3345245,1,1.1236886,4.77554676,5.3345245,5.5345245,5.4345245,1.1236886,4.77554676,5.3345245,1.1236886,4.77554676,5.3345245) names(vals) <- LETTERS[1:16] mp <- barplot(vals, ylim = c(0, 6)) text(mp, vals, labels = vals, pos = 3) Is there any way to round up those numbers?

[R] how to include bar values in a barplot?
How do I include bar values in a barplot (or other R graphics, where this could be applicable)?

[R] using loops to create multiple images
I have a data.frame with ~100 columns and I need a barplot for each column
produced and saved in some directory.
I am not sure it is possible - so please help me.
this is my loop that does not work...
vars <- list (substitute (G01_01), substitute (G01_02), substitute (G01_03),
substitute (G01_04))
results <- data.frame ('Variable Name'=rep (NA, length (vars)),
check.names=FALSE)
for (i in 1:length (vars)) {
barplot(table(i),xlab=i,ylab="Nuomonės")
dev.copy(png, filename="/my/dir/barplot.i.png", height=600, width=600)
dev.off()
}
questions:
Is it possible to use the i somewhere _within_ a file name? (like it is
possible in other programming or scripting languages?)
Since I hate to type in all the variables (they go from G01_01 to G01_10 and
then from G02_01 to G02_10 and so on), is it possible to shorten this list by
putting there another loop, applying some programming thing or so?

[R] how do I draw such a barplot?
I did not have much success with ggplot2 and reshape libraries, so finally I
managed to work out the graph in a rather complicated way. The only thing I
cannot figure out is, how do I place the legend outside the barplot column
area?
attach(tolerancija.data)
ateist = table(G09_01)
dvasin = table(G09_02)
gamtos = table(G09_03)
kr_klm = table(G09_04)
musulm = table(G09_05)
na_kri = table(G09_06)
pagoni = table(G09_07)
satani = table(G09_08)
rytų_k = table(G09_08)
satani = table(G09_09)
tradic = table(G09_10)
eilutes=cbind(ateist,dvasin,gamtos,krikšč,musulm,kr_klm,na_kri,pagoni,rytų_k,satani,tradic)
barplot(prop.table(eilutes,2),col=c("red3","red2","cyan","green2","green3"),legend.text=c("visiškai
sutinku","nesutinku","abejoju","sutinku","visiškai sutinku"),main="My title")
dettach(tolerancija.data)
However, this is a lot of writing. How do I make into a function to be
reusable?

Hi, I cannot figure out how to draw a certain plot: could someone help me out? I have this data.frame from a survey my.data that looks like something like this: col1 col2 col3 col4 1 5 5 4 5 2 3 5 3 1 3 2 3 4 5 4 3 1 1 2 5 5 5 4 5 6 4 2 5 5 Each row represents a single questionnaire with someone giving his agreement/disagreement with a statement (each column is a statement) that is coded from 1 to 5. I need to draw a barplot giving a visual representation showing differences between the five columns: Each bar should represent a single column, and should be divided into 5 sections, the thickness of each depending on the number of respondents who choose that particular answer. How do I do that? All I have managed to do so far is to produce a barplot of a single column, and that - only with bars side by side... -- Donatas Glodenis http://dg.lapas.info __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

This sequence seems to do the trick, although I do not seem to have a font
URWHelvetica
Anyway, where do i record these lines to make it permanent?
Maybe the explanation was there in Prof Brian Ripley's first email, but I did
not get it somehow...

[R] charset in graphics

[R] elementary statistics with R (rkward?)
Hi, I am trying to learn some basic statistics stuff but I cannot find any elementary statistics exercises using R language. Using RKward would be even better... I need that in analysing sociological data, obtained through questionnairres - findind corelations between variables, relations between different types of data, etc. Could anyone recommend simple tutorials/exercises, available on www for me to work on? I realize it would be much simple to do this introductory stuff with spss, that everyone around me is using here in Lithuania, but I'd really like to learn to do it with R instead... -- Donatas G. __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
