similar to: Defining range of x and y axis in pairs()

Hi list, I have a function which basically is a wrapper of pairs with some useful panel functions. However, I'm having trouble to pass the "xlim" and "ylim" into the function so the x and y axes are in the same scale and 45 degree lines are exactly diagonal. I've looked at some old posts, they didn't help much. I think this is b/c I have multiple panel

Hi, I have the following problem. I wanted to get a matrix of scatterplots and I used pairs. I wanted to add the line y=x in each plot and I created a panel function for this scope. I used points and abline in the following way: ## put y=x in each plot panel.lin<- function(x, y) { points(x,y, pch=21, bg=par("bg"), col = "black",cex=2)

my data are matrix with 3 numeric columns. would like to have pairs plot with scatterplots in the upper with hist at the diag and with correlation at the lower. actually default pairs does almost what I want but looks semi awesome. Especially, i didn't find out how to remove the axes from the lower part where I do only want to display the numeric values correlations there and somehow axes

Greetings R users, I am an R graphics newbie trying to produce a custom trellis plot using pairs() with R 2.7.2. I have spatial data on which I run a geographically weighted regression (gwr, using the -spgwr- package). I want to check the gwr coefficients for multicollinearity and spatial association, following Wheeler and Tiefelsdorf (2005), and I would like to summarize the results of this

With a data frame containing some X & Y variables I can get the between set correlations with cor(X,Y): > cor(NLSY[,1:2], NLSY[3:6]) antisoc hyperact income educ math 0.043381307 -0.07581733 0.25487753 0.2876875 read -0.003735785 -0.07555683 0.09114299 0.1884101 Is there somewhere an analog of pairs(X,Y) that will produce the pairwise plots of each X against each

I have the following problem. I want to use pairs function and get a matrix of scatterplots with the correlations in the upper panel and the ordinary scatterplots in the lower panel. Moreover, I want to have points colored in five differet ways in the lower panel, because I have five subgroups. In order to do that I tried to combine examples on pairs function help. I got a colored matrix

Dear R-users, I am trying to produce (standard and trellis) scatterplots which use the same range of the x and y axes. In addition, I would like the plots to be physically square. Is there one or more specific argument(s) to plot and xyplot what would do that? I have looked at various combinations of asp and pin value, but could not get what I wanted.. Thank you in advance for your help

Hi is there an alternative to par(new), for ading data to a plot for a different y-axis? My problem with par(new=TRUE) is, that it re-defines all axis and labels (as in example 1) and one has to use xlim=... to fix the x-axis. I am looking for something, which simply resets the y-axis, so that a new plot() (or points()/lines()) keeps the x-axis, but re-defines the y-axis. Is there something

Has anyone successfully created a PNG file for a dendrogram? I am able to successfully launch and view a dendrogram in Quartz. However, the dendrogram is quite large (too large to read on a computer screen), so I am trying to save it to a file (1000x4000 pixels) for viewing in other apps. However, whenever I try to initiate a PNG device, I get a "need finitite 'xlim' values"

Hello, I have a customized pairs () fonction as follows that displays correctely my data. ------------------------------------------------------------------------ panel.cor1 <- function (x, y, digits=2, prefix="") { usr <- par("usr"); on.exit(par(usr)) par(usr = c(0, 1, 0, 1)) r <- cor(x, y,use="pairwise.complete.obs",

I have the following R code to create a plot with two y axes. I am essentially trying to plot a price series with a volume series on the same graph. (i.e. to compare price with volume). I can label the first y axis successfully, but the problem is in labeling the 2nd y-axis. Essentially, the label never appears. It seems as though there is not enough margin on the right hand side of

Hi, I am using the following code as an example function to create multiple y-axes on one plot. I have it working fine however, I can't seem to add a label on the second (right) axis. I have tried adding ylab="y2" in the axis call but, that didn't work; any ideas? Thanks, Jesse Code: function() { par(las=1,xaxs="r",mai=c(1,0.75,1,1)) x<-1:10 y1<-x

Hi, I calculating the output of a function when applied to pairs of row from a single matrix or dataframe similar to how cor() and pairs() work. This is the code that I have been using: pairwise.apply <- function(x, FUN, ...){ n <- nrow(x) r <- rownames(x) output <- matrix(NA, nc=n, nr=n, dimnames=list(r, r)) for(i in 1:n){ for(j

Dear mailing list readers! Using R and the plot function I stumbled over this little issue: plot(x=NULL, y=NULL, xlim=range(1:10), ylim=range(1e-9:1), log="y") produces an plot empty plot, where the y-axis is in the specified range. Changing ylim to ylim=range(1e-9:1e-3) creates an y-axis in the range of 1e-12 to 1e-6. This appearance of the y-axis is a

I am using R studio version 0.97.336. I am trying to produce multiple figures based on a large data set (98010 rows). I am creating a plot for each TITLE (related to a variable/station combination). #Create a plot for each Title. Save all plots as jpegs in folder named "SkeenaQfigs" for(i in 1:nlevels(dt$TITLE)){ tmp.title <- subset(dt, TITLE == levels(dt$TITLE)[i]) #save

Hi Rosa something like plot(1,1, sub=expression(lambda^"2")) So with your example, do you want something like plot(c(1:5), CRP7raw[1,], type = "n", xlim=c(1,5), ylim=c(-10,5) , xlab="Day in ICU", ylab="CRP (mg/dL)", sub = mtext(expression(lambda^2))) CRP7graph <- apply(CRP7, 1, lines, col="gray") Cheers Petr >

I am trying to make a x-axis and y-axis titles with both a special character and a subscript. I am not being able to do this. I think its just a placing of my parenthesis, but I've tried (seemingly) everything. Even more, when I try the blog users code it works. Is it because I?m using longitudinal data? Even more. Is it possible to colour each one of the 15 lines with a different

Hello, I'm trying to pull off a certain graph using splom, and can't quite get my panel functions right. Basically, the equivalent using pairs would be something like this (using iris data set as an example): panel.corval <- function(x, y, digits=2, prefix="", cex.cor,col,pch) { usr <- par("usr"); on.exit(par(usr)) par(usr = c(0, 1, 0, 1))

Hi dear list, I'm scrambling with this: i have a p-dimensional data frame for which i want to have a pairs() plot, with ellipse added in each lower.panel. I want the ellipse's parameter (mu, sigma) to be extracted from the appropriate entries in a pre-computed matrix ("dab" in the code below). Can it be done ?
