[R] converting character to numeric
I'm trying to convert data from character to numeric. I've imported data as a csv file, I'm assuming that the import is a database - are all the columns in a database considered vectors and that they can be operated on individually Therefore I've tried the following mydata - as.numeric(mydata$apples) when i then look at mydata again the named column is still in character format if i do mydata2 - as.numeric(mydata$apples) the new object mydata2 is empty. Am i missing something about the structure of R? alina [[alternative HTML version deleted]] __ R-help@r-project.org 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.
[R] importing a file
I haven't used R in a couple of years, and now am trying something as simple as importing a csv file and am running into problems right away. * mydata - read.csv (Wordata1.csv, sep=) Error in read.table(file = file, header = header, sep = sep, quote = quote, : object 'Wordata1.csv' not found *I've tried in both as as read.csv and read.table and still get the same message. I've double-checked that I'm in the right directory using getwd() and indeed I am. Any ideas on what might be causing this error message? Can it be something in the format of the file? (I've looked through the archives and didn't see anything that might explain it) thank you!!!

[R] colored maps again
I'm trying to create a colored map that would show the number of students per state. My data frame consists of two columns - state and count. I'm using the following code library(maps) map(usa) library(plotrix) state.col-color.scale(gre$count,0,0,c(0,1)) map(state,fill=TRUE,col=state.col) I'm getting a map, but the values are not being mapped to correct states. What do I need to do to fix that?

[R] color maps with counts
I have yet another question concerning maps. This time I want to create a colored map of number of students by state. Can this be done using palettes in Rcolor brewer, is there some other way? I've been looking through R archives, but am still really at a loss here, so all help will be much appreciated. Thank you!

[R] creating a map
I'm trying to create a fairly basic map using R. What i want to get is the map of the country with circles representing a count of students in each state. What I've done so far is as following - map(state) symbols(data1$count,circles=log(data1$count)*3,fg=col,bg=col,add=T,inches=F) this gives me the map of the country, but one that's not populated by my counts. Does anyone know what I'm doing wrong? Also, if anyone can recommend a good reference for creating maps in R, I'd really appreciate that. thank you [[alternative HTML version deleted]] __ R-help@r-project.org 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.
Re: [R] creating a map
Thanks Greg, do you know where i can find the sate.center dataset that you mention? On Tue, Feb 17, 2009 at 12:28 PM, Greg Snow greg.s...@imail.org wrote: You need to give the symbols function the locations where you want the centers of the circles to be. Some datesets with map information also have centers of the states that you can use, for the USA, there is the state.center dataset that may work for you, or the maptools package function get.Pcent will compute a center for polygons (there are probably other similar functions in other packages). For adding circles to a map of the USA, you may want to look at the state.vbm data in the TeachingDemos package (works with maptools package), but you will need to computer the centers of the polygons, they don't match state.center or others.
