Hi all, suppose there is a vector y with rownames: > y cond1 cond2 cond3 cond4 78.952 87.308 86.490 74.040 how can I easily plot this vector using the rownames? plot(y) gives me a plot with a x-axis from 1 to 4 in 0.5 steps, also plot(rownames(y), y) and plot(y ~ rownames(y) don't work. I know I can build a x-axis with axis(1, ...), but in this case I need a character string like

Hello, I am trying to create a stripchart for my data, where y axis labels are characters (ie,names of cities). I would like to change the orientation of the y - axis labels, ie perpendicular to y axis. Below is the code i am using: par(srt=90) with(ozone.ne.trim, stripchart(Median~City,main = "stripchart(ozone)")) The par option doesn't seem to working. Kindly help. Thanks

Is there a way to create a 'bubble plot' in R? For example, if we define the following data frame containing the level of y observed for 5 patients at three time points: time<-c(rep('time 1',5),rep('time 2',5),rep('time 3',5))

I really like to use R for all my graphs, and as I work with stable isotopes I want to have a proper chemical notation in my plots I have looked at ?plotmath, but didn't find the answer and also searched the R website. ------------------------------------------------------------------------ -- plot(1:10,xlab=expression(^{14}*C)) # I want to have a superscript with nothing in front, but it

Dear R-team As I didn't get any answer to my bug-report last week I have taken the effort and extracted a minimal data set from my data (see below) where the following bug occurs: > glm(SKR.ein.aus ~ ., family = binomial, data = bugdata, na.action = na.omit) Error in names<-.default(*tmp*, value = ynames) : names attribute must be the same length as the vector In addition: Warning

Hello, I've been looking through ?phantom and ?expression and this forum for examples of how I might be able to manipulate some of the names that appear on the y-axis of the barplot below. For example, the "gw" in "ECgw" would appear as a subscript...or "qr" would be the theta symbol followed by subscript "r". My attempts haven't even come close

Dear R users, I am looking for the source code of the implementation of ppr (Projection Pursuit Regression) in R. It will be great if citations of the source papers on which the implementation is based, are also provided.

Hi, I want to test for a contrast from a regression where I am regressing the columns of a matrix. In short, the following. X <- matrix(rnorm(50),10,5) Y <- matrix(rnorm(50),10,5) lm(Y~X) Call: lm(formula = Y ~ X) Coefficients: [,1] [,2] [,3] [,4] [,5] (Intercept) 0.3350 -0.1989 -0.1932 0.7528 0.0727 X1 0.2007 -0.8505 0.0520

I want to make a 2x2 plot on a single page, using stripplot() and boxplot(). I tried the following two alternatives with mfrow() and layout(), but none of them worked. library(lattice) par(mfrow=c(2,2)) boxplot(X1 ~ Y, data=tst1, horizontal=T, las=1) boxplot(X2 ~ Y, data=tst1, horizontal=T, las=1) stripplot(Y ~ X1, data=tst1) stripplot(Y ~ X2, data=tst1) par(mfrow=c(1,1)) nf <-

G'day all, I had a look at the GLM code of R (1.4.1) and I believe that there are problems with the function "glm.fit" that may bite in rare circumstances. Note, I have no data set with which I ran into trouble. This report is solely based on having a look at the code. Below I append a listing of the glm.fit function as produced by my system. I have added line numbers so that I

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

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?

Hi, I am trying to plot a graph using stripchart() - my x-axis is categorical and my y-axis is numerical. I would like to reverse the order of my y-axis (i.e. with 0 at the top left and increasing numbers moving downward towards the bottom left corner). My data are subsetted into 3 categories that I've plotted on 1 graph using stripchart(add=TRUE) option. Thanks for any assistance, Regards,

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

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, Can R produce dot plots like the one of the following picture: http://en.wikipedia.org/wiki/Image:Dotplot_of_random_values.png ? I have tried dotchart, but no success. Thanks in advance, Paul

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:

I'm not understanding something. I'm trying to add xlab & ylab to a balloon plot of a table object. From docs I thought following should work: require(gplots) # From balloonplot example: # Create an example using table xnames <- sample( letters[1:3], 50, replace=2) ynames <- sample( 1:5, 50, replace=2) tab <- table(xnames, ynames) balloonplot(tab)

Hi, I'd like to remove the axes from a plot produced by stripchart(). However, when trying stripchart(..., axes = FALSE), I get the error meassage Error in stripchart(hypokvot1 ~ treatment, "jitter", pch = 1, vert = TRUE, : unused argument(s) (axes ...) using R 1.8.1 on Windows. Can it be done some other way? If not, maybe this functionality can be added to a future version of

Hello, I would like to know if (as the usa map with Splus), it is possible with R to plot the french map and to add points (representing towns for instance) on the figure in the appropriate (x,y) system. Thank you. Nathalie Peyrard
