I'm having the exact problem outlined in a previous post from 2005 - unfortunately the post was never answered: http://tolstoy.newcastle.edu.au/R/help/05/10/15055.html When running: lm2=lars(x2,y,type="lasso",use.Gram=F) I get an error: Error in if (zmin < gamhat) { : missing value where TRUE/FALSE needed ...when running lasso via lars() on a 67x3795 set of predictors. I hacked the lars() function to print out the zmin, gamhat, and also z1 values (used to calculate zmin) - it seems that the error comes up during the lasso process when all the...

I'm trying to read a binary file created by a fortran code using readBin and readChar. Everything reads fine (integers and strings) except for double precision numbers, they are read as huge or very small number (1E-250,...). I tried various endianness, swap, But nothing has worked so far. I also tried on R 64 bit for linux and windows (R 2.14) and R 2.11 on windows XP 32 bit. Any help would

...lot2 plot below, the pixel located at [1,3] would be outlined by a black square since the value at sig[1,3] == 1. This is my first foray into ggplot2, and so far the googles hasn't helped me determine if this is possible. Thanks, Eric PS, my attempt to stretch the color scale such that (-1 * zmin) = zmax = max(abs(m1)) has failed (i.e., ..., autoscale = FALSE, zmin = -1 * zmax1, zmax = zmax1), any pointers on this would greatly appreciated as well. # Import packages library(ggplot2) library(RColorBrewer) library(reshape2) m1 <- matrix(c( -0.0024, -0.0031, -0.0021, -0.0034, -0.0060, -1....

Dear All I want to plot a kind of figures, which can interactive with user. For example, i have a matirx which can be showed by image function. i.e. we can compare the value depend on different colors. However, the change of colors depend on the range of value. Nowaday, i want to set a bar, which can be moved by user such that the user can obtain the appropriate range. Does anyone suggest me which

Hello I'm using rainbow function to generate 10 colors for the plot and it is difficult to tell the neighboring colors from each other. How can I make the colors more differently. Thanks Zhaoming [[alternative HTML version deleted]]

Hi Eric, you can use an annotate-layer, eg ind<-which(sig>0,arr.ind = T) ggplot(m1.melted, aes(x = Month, y = Site, fill = Concentration), autoscale = FALSE, zmin = -1 * zmax1, zmax = zmax1) + geom_tile() + coord_equal() + scale_fill_gradient2(low = "darkred", mid = "white", high = "darkblue", midpoint = 0) +annotate("rect",ymin=ind[,"row&q...

Hi Everyone, I have csv file which is in following format xmin,xmax,ymin,ymax,zmin,zmax I want to plot 3d graph with all the all octants being displayed as well. Any idea? I have used scatterplot3d package but it does not seem to have anything by which i can draw "octants" inside cube as well. Thanks [[alternative HTML version deleted]]

...m also wondering if you have any pointers for how I might stretch the color scale so that the max and min values are the same? Right now, the min is -0.064 and the max is something closer to 0.04. As you can see in what I sent, I tried adding: zmax1 = max(abs(m1)) ggplot(..., autoscale = FALSE, zmin = -1 * zmax1, zmax = zmax1) + ... to ggplot, but I'm either using the wrong arguments or have not added them to the correct spot. I haven't been able to find the fix for this and would very much appreciate any further guidance you can offer for this last fix. [[alternative HTML version...

Functionally identical but much simpler. Should also better integrate with future layer/viewport changes/fixes.

Hi all, I've got a set of gene expression data, and I'm plotting several heatmaps for subsets of the whole set. I'd like the heatmaps to have the same color distribution, so that comparisons may be made (roughly) across heatmaps; this would require that the color distribution and distance functions be based on the entire dataset, rather than on individual subsets.
