...h entry is either zero or one (can hardly get any simpler). Now, I would like to plot it as a 'chessboard' where every matrix entry is a black (1) or white (0) square. Whatever tool I use to plot it, it should not try to interpolate the data at all. I found some online references http://www.phaget4.org/R/image_matrix.html but probably I can resort to something much simpler. Can anyone provide me with a simple example I can modify later on? Many thanks Lorenzo

Hi, I am looking for options to plot the following type of matrices: "A" "B" "C" "D" "A" "A" "C" "C" "A" "A" "A" "C" as a image like this: http://www.phaget4.org/R/image002.jpg

Dear all, Using the code I got from the link ( http://www.phaget4.org/R/image_matrix.html), I obtained a nice plot that suits me. However, adding axes labels proved difficult for me . I have succeeded in adding a few things to the plot function so as to get what a better plot. Other things work but ylab="days" did not reflect. It will be great if somebo...

r-help-es@r-project.org Hola!! Estoy trabajando con una función del tipo h(x)''B, donde h(x) es un vector columna de q entradas, de igual manera B es un vector columna de dimensión q. Quiero graficar h(x)''B para alguna h(x), por ejemplo h<-function(x) matrix(c(1,x,x^2,x^3), ncol=1) B es un vector columna fijo B=matrix(c(1,2,1,3),ncol=1) Para graficar la función

...CB -0.270 I now want to create a matrix that uses the names from the first column as a "reference", so in the matrix the first row name will be "A" and the first column name will be "B" with a value of 0.102.

Hi I have dataset that consists of two columns AB 0.102 AC -0.002 BA -0.102 BC 0.270 CA 0.002 CB -0.270 I wish to create a matrix so that I can eventually plot the data. A B C A 1 0.102 -0.002 B -0.102 1 0.27 C 0.002 -0.27 1 Any help or guidance would be greatly

Hello, I'm trying to figure out how to create a data object, and then save it with a user-defined name that is input as a command line argument. I know how to create the object and assign it the new name, however, I can't figure out how to refer to the new name for a future operation such as save(). The code below creates an object and uses assign() to give it the user supplied name
