Hi R experts. I performed an Linear Discriminant Analysis (lda) and now I want to plot the first two axes (LDA1 and LDA2). Well MASS package have the plot.lda and pairs.lda to do that. But, they don’t let me personalize them, once they don’t accept the type=’n’ plot. So I start looking at the lda object properties, trying to found out my groups (n=4) axis coordinates, curiously I couldn’t. There

Hi list members. I’ll try to plot the abundance means of nine transects as lines, with five points on each transect (A to I). I will also need to plot for each point, it’s standard deviation (once each point will have tree replicates) as whiskers. Another problem will be that all the points should exist for each transect, but we know that six of the nine transects will have blanks (A1, A2, A3, -,

Hi list, I was searching how to properly write a command line for a mixed ANOVA. Well honestly, there are so many material on the older post of the list that just confused me. I have five factors. Season (fixed) Beach (fixed) Line (fixed) Block (random) Strata (random) nested in Block And for each of the tree strata per block I got 3 replicates. I saw lots of things about

Hi list, I would like to know if there is a way in R to execute a post-hoc test (factor levels comparison, like Tukey for ANOVA) of a non-parametric analysis of variance (kruskal.test() function object). I was looking for something like the Dunn Test. I’ve searched the internet but nothing seemed to define a way to it. Do You have any suggestion? Other equivalent test maybe! Thanks in

Hi, I'm a beginner with R, but I'm getting excellent results with it. Well I've got an capscale object (vegan package) and I want to made a biplot with symbols representing six groups of areas. With the plot.cca function and some par attributes (like 'labels') I was able to substitute the samples names for keyboard symbols ('x','o','#',ect), but it's

He everybody, Well I have a biplot CCA-like origined from plot.cca (vegan package). I need to rotate on y axis the lines and symbols of constrained and sites representation. If I do that on an image editor, I rotate everything, including titles, axes labels and positions. I just need to rotate the inner par and keep the variables names (constrained) and symbols in the new positions but with the

Oh sorry. An example say lots more than words. The data below, when submitted to twoord.plot return the mentioned error. Rain are bars and Salt lines, the bars appear and the error occurs with the salt data.

Hi list. I would like to know if someone had already successfully loaded and Arc/Info Ungenerated (.dat – extracted from http://rimmer.ngdc.noaa.gov/mgg/coast/getcoast.html) file on R. I’m able to do so with shape files using maptools functions, but these ungenerated data are making me crazy. I don’t have any of ArcGIS tools (one of them probably can do that), and I can’t find any free tool that

Hi list. I'm trying to plot a graph "by" factors. Exactly, the x axis are my depths (as.factor), my left y axis are my transects (also as.factor) and I want to plot the mean and standard deviation (three samples per factor combination) of my SW (numeric) variable. The second y axis (at the right) will, probably, need to be displayed several times (for both left y axis

Hi List, here I go again. Well I need to save plotted objects as .eps using the postscript() function, well I can do that but all resulting object are perfect squared dimensions (x = y). I need a rectangular output something like x = 2y dimension. Is it possible? The I’m new to R and postscript image format! I’m doing this…

Hi list. I was saving my modified pairs graphic using a custom panel from the R Graphics site, and I got an interesting difference in the final image when I save it as eps or png. This custom panel make possible to show at the left side of the pairs plot the p-value as symbol and the correlation r value with its cex proportional to the r value itself. Well, when saving as a png file

Hi list, Well, this time I’ve a doubt with mapping generation. I was already able to read and plot shapefiles, plot point on this map. All this without any problems, but now I want to do something that I think, only Golden Software Surfer is capable of. I would like to plot a kriging result on the existing map (map script below). Well I looked for on the net, but I was not able to be sure of

Hi List, I would appreciate any suggestion on how can I make a text I’ve inserted in a plot show some contrast? With this I mean that I have a white text on a plot and I would like to make a tiny border around it in black, so even being small sized and the entire graphic being small in the text page I’ll insert it. It will be visible. Well I tried inserting a box() function inside the text()

Hi List. It may be a very simple question, but I couldn’t find an answer on the internet. Which function (maybe in a specific package) would I use to perform a Cochran C Test for Homogeneity of Variances? Stats package have the mantelhaen.test, but I’m “almost sure” that It’s not what I want, it’s probably the Cochran Q Test. So, any ideas? Thank you for the pacience.

Hi List, I’m using the vegan function specaccum to produce a rarefaction curve. In the function’s help it says: “Function ‘specaccum’ finds species accumulation curves or the number of species for a certain number of sampled sites or individuals”. Well, I would like to finds this curve for individuals, but when I compute it the function (using the ‘rarefaction’ method) gives me Sites, Richness

Hi list, recently, for didactic reasons, I had the need to change a cluster topology (just the order of my groups, defined in an height of choice), not the results, obviously. Well I’m looking at hclust or agnes (cluster package) objects for something that defines the line breakings of the graphics, so I could try something to change this plot ordering. But, I’m unable to figure that out. Is

Hi List, I would like to embed some fonts (AFM format) on 324 eps files produced by a R loop, I’m able to do so one-by-one with the following command: embedFonts('C:/Users/Rodrigo/Documents/UFPR/Micropaleontologia/Potiguar/Cata logo/Mapas/EPS/Example.eps', outfile='C:/Users/Rodrigo/Documents/UFPR/Micropaleontologia/Potiguar/Catalog o/Mapas/EPS/Example2.eps',

Hi List. I've to perform a sequence of conditional sampling without repetition from a very simple data frame. It contains the samples and people names (which picked the sample). Something like this (but much more longer): Sample Picker 4ME1B2 B Ana 4ME1C1 B Ana 4ME1D2 C Ana 4ME1E2 C Ana 4ME1E3 A Ana 4ME2A1 C Ana 4ME2D2 B Ana 4CME3 B Ingrid 4CME7 C Ana
