Please, is there an R function /package that allows for 3D stairway plots like the attached one ? In addition, how can I overlay a parametric grid plot??

Dear, I have XYZ data available in a MySQL database. I get it out, can plot the data with the plot() function, load it into a geoR datastructure. But what I actually would like to do is a simple contouring of the data based on a no Kriging interpolation such as TIN based. I know the first thing I shold do is interpolate a full matrix for the region I have my points for, then contour should

R Users, I am using the AKIMA contrib package to generate a 2D colored contour plot. The code generates a contour value color legend adjacent the plot based on the range of Z values in the plot. Is there some way to make the association between Z values and color scale absolute rather than relative i.e., I want dark green to always mean Z = 4.00 even if I don't

R- Users: Can someone indicate what I am during wrong? This is a script essentially from Venerable & Ripley's text on interpolating a surface with loess function but I can not get it to run. Thanks.

Dear R'Helpers and Colleagues, I have looked in the documentation, asked to some colleagues in the lab, but was unable to solve the following difficulty. I am running R on a iMac G5 with OS 10.4. The file below (73 rows x 144 col) shows the values of a climatic index on the globe with a grid of 2,5 ? x 2,5 ? (NA = no value): ? With image() and map() and running the following

Hi all, Is there any way to generate a scatter plot with Gruff? I had a look at it but it seemed to me to only want a category type x axis.

Hello: I would like to make h-scatter plot. My data looks like as follow: x, y, z, 12.0, 11.2, 12, 10.21, 5.42, 8, 5.12, -8.25, 7, .... I want to make h-scatter plot for the z values by difference distance h from 1 to 20. There are 1023 observations. Do I need to change data class from data-frame to others? I am not sure we can make h-scatter plot in R. Have a nice day. HongSU.

I want to create some 3D scatter plot with a diagonal line. In addition, I'd like to have those points plus the diagonal line projected to those three planes (xy, yz and xz). Which package can I use to achieve this, scatterplot3d or something else? Thanks, Gang [[alternative HTML version deleted]]

Dear R Is there a way to apply row names as labels to a scatter plot matrix , I tried pairs(dogs, labels=row.names) Error in strwidth(labels, "user") : cannot coerce type closure to character vector I'm not sure what this means, however maybe you might know of a way to do this? brett stansfield

Hello, I am trying to draw a convex-polygon (envelope) connecting the outer points (of a particular class) in a scatter plot [which I want to do to illustrate the range of a particular type of samples in an ordination plot]. Is there any function to plot this kind of polygon? Kind regards Zlatko Petrin

Hi, I am trying to create a set of scatter diagrams with coplot, and I want to use different symbols for each class of points (depending on where the data point came from). I have the array with the required symbols, but I am not sure how to pass that array to the panel function, and whether I need to modify my panel function. I would appreciate any suggestion. Better yet, an example

Dear all, When making a plot with the command plot(xVector, yVector), there are many points that collide on the same place in the plot. In order to make this plot clearer, I have been looking for a way to colour the points based on the number of points that fall onto each other. If only one point falls on a particular location, make it gray, if many points fall, make it black. I tried to search

Hi, there: Does anyone know how to specify the ranges in the axises when I make scatter plots using pairs()? In the general plot function, I can use xlim and ylim option. But how can I do this if I use pairs()? Thanks. Yulei [[alternative HTML version deleted]]

Hallo, I would like to add the marginal distributions along the X and the Y axis to a scatter plot. Can anybody help me, please? Thank you, Paolo -- Paolo Bulla Istituto di Metodi Quantitativi Universit?? "L. Bocconi" viale Isonzo 25 20136 Milano paolo.bulla at unibocconi.it

Hi, Could anyone give suggestions how to plot a scatter plot with 1 standard deviation for each point. To make it clearer, here is a simple example: the scatterplot is plot(X, Y), but I want to add 1 standard deviation according to the value of Z for each Y. X Y Z 1 3.5 1.1 . . . . . . . . . Thanks a lot in advance. FD [[alternative HTML

Hello R-helpers, I'm plotting a scatter plot matrix, but have more variables to consider than will legibly fit on one page. I'd appreciate some help on how I can persuade pairs or splom to plot the full matrix of plots over several pages. With thanks, John Field

Hi,   I would like to draw a box at each corner of lower 10% and upper 10% in the scatter plot on(0,1)*(0,1)  to indicate the lower and upper tail.  I hope somebody can help me.   Here is my code: ## scatter plot plot(hume_uni[,2],beec_uni[,2], pch=19, xlab="Hume_uni", ylab="Beec_uni", col= "blue")  title(main="Scatter plot of uniformised data of Hume and

#Hi all, #Using the example data that follows, can someone please show me how to get a scatterplot of points with #error bars in the Y direction. something like this works for one Y: xYplot(Cbind(y1, l1, u1) ~x1, data=y) #but this: xYplot(Cbind(y1, l1, u1) + Cbind(y2, l2, u2)~x1, data=y) # doesn't give me what I would have expected, which is both sets of points to have their respective

Dear R-helpers: I, an entry level R user, wonder how make a 3d scatter plot with both error bars and a flexibly fitted surface. Can anyone eligthen me? Many Thanks in advance. -Sean [[alternative HTML version deleted]]
