Hi, I have a data set of points which are represented by 3 variables x,y,z where x is the position of the point on the x-absciss and y on the y-absciss. Each of my points has a value z, which I want to be displayed as follows: the more z is high, the more the color on the map is dark. How can I achieve this ?

If you need a newer version of R for installing the latest version of plyr, perhaps another solution (as very new versions of R -2-11.0- will come out soonly ) , which needs 2 lines of bash!, might be to download an old version of plyr : wget \ http://cran.at.r-project.org/src/contrib/Archive/plyr/plyr_0.1.1.tar.gz and install it R CMD INSTALL plyr_0.1.1.tar.gz (and then reshape

I want to make illustrations a la boxplot for a data material with several groups. Some of the groups are very small, so a boxplot doesn't make sense. I would like to use stripchart for these groups. On the other hand, some of the groups are very large, so for them stripchart isn't so good. So my question is: Is it possible to combine boxplots and and stripcharts in one figure? (Of course,

Hi all, I I need to manipulate the x axis in a stripchart. I will use one of the data sets included in R to explain what I need to do. attach(ToothGrowth) stripchart(len[supp=='VC']~dose[supp=='VC'], vertical=TRUE, group.names=c('A','A','A')) stripchart(len[supp=='OJ']~dose[supp=='OJ'], add=TRUE, vertical=TRUE, at=c(1:3)+.1,

Dear all, consider: ### x <- round(rnorm(50)) stripchart(x, pch = 21, col = "black", bg = "pink", method = "jitter") points(0.5, 1, pch = 21, col = "black", bg = "pink", cex = 2) ### Under R 2.9.0 the points produced by stripchart are not colored, while points() gives the desidered output (magnified here by cex). I found a simple workaround

Hello: I use R with MAC I have a simple data table, numeric and text columns, named dt. The table is imported through read.csv from a csv file. Row numbers are automatically assigned, header is set to TRUE. there are 599 rows and several columns. I am trying to plot using the stripchart command: one numeric variable (say dt$fnatg) vs a text column (say dt$pat). dt$pat contains one of 3 values:

Dear all - With the following code I get Boxplots and Stripcharts in one Plot: with(InsectSprays, boxplot(count ~ spray, boxwex = 0.3)) with(InsectSprays, stripchart(count ~ spray, col = "red", vertical = TRUE, add = TRUE)) But the dots from the stripchart are plotted over the Boxes. Is there any possibility to have Stripchart and Boxplots side-by-side, i.e. to move boxplots and/or

Hello, I frequently use stripchart to summarise data. Recently I wished to plot a stripchart on a log scale, so modified stripchart locally. The change is small, just adding log="" to the function call and then changing line 42 of src/library/base/R/stripchart.R from: plot(xlim, ylim, type="n", ann=FALSE, axes=FALSE) to: plot(xlim, ylim, type="n",

hi, I want to plot a dotplot graph but unfortunately R does not have it any more. It suggest to use either the stripchart or the dotchart and i prefer to play around with the stripchart graph. Sadly, the result is not like i want where I'm actually wants the plots/points were scattered around the x-axis. Plus, from the results shows that and the x-axis gave a very large scale, i.e

Hi Ross - I believe I was wrong in thinking that passing via the ... list to stripchart() was ever allowed. Here are patches: Add ... to the argument list Add, at the beginning of the function: pars <- list(...) There are two calls to axis(). Modify these to: axis(1, at = at, labels = names(groups), las=pars$las) axis(2, at = at, labels = names(groups), las=pars$las) Also

Hi everybody, I'm a new member of the list. I'm just starting to use R. I'm looking for information about stripcharts. I didn't find a lot on the web.

I succeeded to create one

Dear all, I would like to ask if it possible to draw a median line in a Stripchart, either using the built-in STRIPCHART function or with another package. I was expecting stripchart() to work more or less like boxplot(), but I couldn't find an easy way to draw a mean or median line, neither I found this option in other packages. Could somebody help?
