[R] the puzzle of eigenvector and eigenvalue

Dear all I am so glad the R can provide the efficient calculate about eigenvector and eigenvalue. However, i have some puzzle about the procedure of eigen. Fristly, what kind of procedue does the R utilize such that the eigen are obtained? For example, A=matrix(c(1,2,4,3),2,2) we can define the eig

[R] the definition of eigenvector in R

Dear All i have a little puzzle about eigenvector in the R. As we know that the eigenvector can be displayed on several form. For example A=matrix(c(1,2,4,3),2,2) if we want to get the eigenvalue and eigenvector, the code followed eigen(A) $values [1] 5 -1 $vectors [,1] [,2] [1

Dear all when the program is runing, we can realize that the memory size will be asked more and more.. Therefore, we could meet the significant problem, such as out off memory size. However, even if i rm() some variables that i will not use it anymore, the memory size still not enough. By the way,

[R] how to rotate the histogram

Dear all I want to combine two figures on one plot. First figure display the data distribution. The x-axis of first figure is individual's ranking and the y-axis of first figure is probability. However, the second figure is a histogram about probability. In order to make the figure more clearly, i

[R] how to make the figure more clearly

Dear all when i draw some figures by R, i try to use "jpeg" to display my result. However, it isn't still clear as i want. Especially when i compare the origial figures by R and the ".jpeg" file the code is follwed jpeg(filename=,width = 1200, height = 800, pointsize = 14) .. dev.o
