Calculate numerically the expected value given a cdfcalc.mean.from.F.fun
Some functions that are useful for coding Looks through all loaded functions and searches for global variables that are used within the functions this is a common source for errorscheck.global.vars
Clones an environment and its childrenclone.environment
Generates a matrix in which all cols are equal to colcol.matrix

Helper function to discretize a continous distribution. F.vec is a finite vector containing the value of the cdf at M different points. The function generates an M dimension vector of probabilities summing up to 1 that discretize the distributiondiscretize.given.F.vec
Finds position where the function f becomes zero First tries find.root and if this fails tries optimizefindzero
Gives the corresponding rows for a permutated grid.matrix given a permutation x.perm of the elements of the original list xgrid.matrix.permutation
Transforms a grid in long format into a matrixgrid.to.matrix

Some functions that are useful for manipulating or creating matrices and data.frames and working with lists of vectors, lists of lists or lists of matrices Transforms a matrix into grid in long formatmatrix.to.grid
Some functions that are useful for lists and environments in particular generating, transforming, copying and assigning values Creates a list that is named by the names of its argumentsnamed.list

Paste together rows of a matrix or data.framepaste.matrix.rows
Plot several linesplot.multi.lines
rbinds a list of matrices, a list of lists, or a list of vectors into a data.frame (or matrix) each column is a list Assume that all columns in the sublists are in the same orderrbind.list
