...about 100 data points per gene (columns). I am only used to loading preprepared microarray data with all the t's crossed and i's dotted, with the read.maimages command. Can anyone help me out with this silly-sounding "challenge"? Sincerely - in the truest sense - Norman Goodacre

...ne) with a given probability for each transition. In this case there'd be 16 different kinds, each with a different weight. Given a transition matrix (4x4) filled with all transition probabilities of course, how can I generate a random sequence of a given length, say 200? -Norman Goodacre --------------------------------- [[alternative HTML version deleted]]

...a vector of x values I would have thought that fn should return a vector full of y values for the x values entered as the second argument. If the function just takes one value at a time and outputs a scalar, how can I specify for fn which x value, of the vector x, to take? Sincerely, Norman Goodacre
