Hello!!! I have a folder (C:/R/) with matrix files, named by number, i.e. 0.mat, 1.mat,...,1250.mat. In this case, they are 5x5 simetric matrices. I would like to compute a property for each matrix and put calculated values into a data frame for posterior ploting and printing. Below there is an example for 7 matrices (0.mat..6.mat) #define data frame L <- data.frame(frame=numeric(7),

Hello!!! I have a question about clustering. I'll present my problem first. I have a simulation of a protein trayectory (a file with a time series of protein 3D-coordinates), from it I can calculate the Root Mean Square desviation (RMSD) beetween any pair of structures in the trayectory, which is a rough idea of 3D similarity beetween them. If for every conformation (trayectory frame) I
