Dear R-help members. I am an 'R-learner' (about 6 hours so far) using the lattice library to create a ranked dotplot and am colour coding the dots by a variable called "Commodity". However when i use autokey to make a legend the size (cex) and symbol (pch) do not match what is on the dotplot. Code is below and image attached library("lattice") Cal_dat <-

Dear R helpers I'm trying to make up some labels for plot from this vector BndY<-seq(from = 18900,to= 19700, by = 50) using Ylab<-for(i in BndY) {c((paste(i," to ",i+50,"mN")))} but the vector created is NULL However if i use for(i in BndY) {print(c(paste(i," to ",i+50,"mN")))} I can see the for loop is making the labels I'm looking for

Dear R helpers I wish to move the main title, which appears on a dotplot to be right aligned with the left axis. Is there are parameter associated with dotplot 'main' that allows the title to be placed where I want it? Code snippet relating to dotplot is below. with(Cal_dat, dotplot(reorder(paste(Mine,Company), Resc_Gt) ~ Resc_Gt, fill_var = Commodity,

Dear R helpers I would like to plot a string of points as a polygon in xyplot. I'm a bit lost as to how to get the points plotting in the correct order. I would also like some hints on how to render or fill the polygon. Scrpt below and data file attached Thanks Markm library("lattice") # set size of the window windows(height=7, width=10,rescale=c("fixed"))

Dear R helpers I would like to move the x-axis labels, which plot automatically at the base of a dot plot to the top of the plot. Is there a way to do this? Code snippet below with(Cal_dat, dotplot(reorder(paste(Mine,Company), Resc_Gt) ~ Resc_Gt, fill_var = Commodity, pch_var = factor(Year), xlab_var = factor(Company), pch = c(21, 22, 23),

I've been building a ranked dot plot for several days now and am sorting the data using the reorder command. What I don't understand is how reorder works when mutiple varibles are plotted by grouping. In the example below I'm using re-order to sort by a variable name Resv_Prop, but I'm plotting up to three different values of Resv_prop (different Year values) for each factor.

Dear R help group I've been working on this plot for a while now and now getting around to the minor adjusments. I would like to be able to put a border and background fill around the legend in this plot. I understand the legend 'bty' should do this have this capablity but not sure how the syntax works in this case ###### initalise library("lattice")

Dear R helpers I would like to be able to colour code the y-axis labels on a complex dot plot by a variable known as company (of which there are only two). The code is below and data attached. Thanks MarkM library("lattice") library(latticeExtra) # for mergedTrellisLegendGrob() # set size of the window windows(height=10, width=7,rescale=c("fixed")) ##read the data to a

Dear R helpers With some help from R-help I've moved the x-scale to the top of a lattice plot using...'alternating' scales = list(x = list(log = 10),alternating=2), but now I cannot seem to find a way to move the x-axis label to the top ?

Dear R helpers I'm attempting to create a matrix of scatterplots with X-Y mean lines and regression lines added to each plot in the matrix. I have managed to create the first plot I would like using scatterplot but have run into an odd result when I use par() to set up the page to take multiple plot. Specifically, the mean and regression lines appear to plot in the second plot window, not

Dear R helpers I'm experimenting with the 'kohonen' package and have two questions. I've been following examples in the package manual and the paper from the Journal of Geostatistical software (October 2007, Volume 21, Issue 5.). I've set up a file with the 'animals' data (see attached file) which I used test a SOM routine I wrote in Fortran some years ago. The

Dear R helpers I would like to plot vertical reference lines for yearly averages the variable being plotted. In this case there are three years 2002, 2009 and 2010 for a variable Resc_Gt. I've attempted to get the 2002 mean plotting (2.27) using the 'abline' command but no joy. Ideally I would like to be able to compute and plot the means of the three years automatically using a

Dear R help(ers). I'm an R-learner (about 10 hours now) trying to make a ranked dot plot where the symbols are coded by two variables concurrently. I'm trying to use Deepanyan Sarkar's book 'Lattice' as a guide but get the feeling it is a bit advanced for my level of understanding. I have three questions Q1. Right now I like to know how to get the dual coding working
