similar to: Plot OctTree

Using the small reproducible example below, I'd like to know if one can somehow use the matrix "sig" (defined below) to add a black outline (with lwd=2) to all pixels with a corresponding value of 1 in the matrix 'sig'? So for example, in the ggplot2 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

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",

I apprecaite the guidance Eik, that works great! I'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

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

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]]

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. Does

I found it useful to have contour be able to do line widths ... hope that the guts haven't changed an enormous amount in the current development version ... the patches are relatively trivial, mostly going by analogy with lty and col (although in my ignorance it took me a while to figure out what UNPROTECT(2) was and why it should be changed to UNPROTECT(3) ... hope this is useful.

Hi, I am new to R and I want to know how to use C code which contains two functions one called inside another.I know that how to use C code in R if it has only one function but dont know how to do it in above case. I want to use the same in R .My C code is as follows. //#include <R.h> void sayHello(); void g(); void sayhello() { Rprintf("Hello world %d\n",global); } void

[Sorry, resending with a proper subject line!] Hi Guru's... I have a set of points that may lie along any of the x, y and z axes in a Cartesian coordinate system. I am hoping that a function exists which will determine if any two selected points are on different axes, i.e, if the one of the points is on x and the other on y or z, not elsewhere on the x axis. Put another way, I need

Hi, I am new to R and I want to plot points on the Map of New York . I also want to divide map of New York into small grids(not fixed) .I want that these point should be plotted from a file.How can I do it?Any help would be greatly appreciated. Thanks Jaimin [[alternative HTML version deleted]]

Could any one tell me how to implement QuadTree in R? Or are there any packages avaialble to implement it in R. [[alternative HTML version deleted]]

Hello Everyone, I am new to R and would like to create a quad tree in R. However the problem is that I don't think R has pointers. Is there any way to create a tree in R? Thanks [[alternative HTML version deleted]]
