Re: [R] No color in plotting
Hi Without some reproducible example you hardly get any answer. if this works library(ggplot2) p <- ggplot(mtcars, aes(wt, mpg)) p + geom_point() the problem is in your data. If it does not, the problem is elsewhere, including broken R installation.

[R] No color in plotting
Hi I am having a problem with plot () and ggplot (). When I call one of these functions, the plotting area starts to look as though it is working, but nothijg ever is visible. Unless it was a dendrogram. Woth the bar chart, the plotting area just had an x and y axis and nothing else. I tried a bar chart with ggplot and i tried to plot a tree result from rpart (). I couldnt see anything plotted. Is there some way I should be troubleshooting this? Im thinking its an R config I did or didnt do. I really have no idea though.

[R] Using color and plotting characters in a scatterplot matrix [Newbie Help]
Hello guys, I have this data set that I imported into R using a line: This data set consists of 7 columns. The two important columns are the first one called 'thrust' and the last one called 'amtemp'. jet-read.table(jetthrust.txt, fill=T, head=T) I am making a scatterplot matrix simply using the line pairs(jet) The problem is that in the last column of this file which has a header name 'amtemp' I want to sort out the values. I want values: Under 90: To be called low values In between 90 and 100: To be called medium values Larger than 100: To be called high values Then I want those groups of values to be in different colors and different characters on the scatterplot! I tried many ways, And I think I am stuck. I first tried it on a normal plot using the line. plot(thrust~amtemp,jet, subset=(jet$amtemp90), col=1, pch=11) plot(thrust~amtemp,jet, subset=(jet$amtemp100), col=2, pch=12) plot(thrust~amtemp,jet, subset=(jet$amtemp100), col=3, pch=13) It didnt work because it just took the last plot and overwrite it over the last one :( Someone help please. Thanks in advance. -- View this message in context: http://www.nabble.com/Using-color-and-plotting-characters-in-a-scatterplot-matrix--Newbie-Help--tp21824880p21824880.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Using color and plotting characters in a scatterplot matrix [Newbie Help]
I figured out how to do the rest, the only thing I need to do now is to somehow change the numbers which are 90 to a character string low . The values which are between 100 - 90 to convert to character string medium. And the values larger than 100 to convert to character string high. Then I would use this line. plot(thrust~amtemp, jet, col=as.numeric(jet$amtemp), pch=as.numeric(jet$amtemp)) The thing is that I dont know how to convert those numerical values into low medium and high Hmm, but then when I think about it better if its changed to the strings above, it wont remember the exact numerical value. Basically what I want to do is make a scatterplot and then just change the color and the symbol of those 3 groups so they can be distinguished on the graph. -- View this message in context: http://www.nabble.com/Using-color-and-plotting-characters-in-a-scatterplot-matrix--Newbie-Help--tp21824880p21825882.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Using color and plotting characters in a scatterplot matrix [Newbie Help]
First make a factor with the levels. jet$Classes - factor(ifelse(jet$amtemp 90, low, ifelse(jet$amtemp 100, medium, high))) Then make life easier and use ggplot install.packages(ggplot2) library(ggplot2) ggplot(jet, aes(x = amtemp, y = thrust, colour = Classes)) + geom_point() HTH, Thierry ir.
