Am using R on a Linux box and am currently writing an interactive R script. 1. How do I ask a user to press any key to continue ? I used a system call to read but this only works if the Enter key is pressed: print("Press any key to continue") system("read") 2. How do I get a string input from the user? Would like to see an R function, say askget(): delay =

Hi, Is there another way to pass arguments via a vector to arbitrary functions as in the following code example without using a series of if else statements? f <- test(func, x, parms, fargs1, fargs2, ...) { # parms is a vector of parameters to func. # ... is for use by f, not by func. n <- length(parms) if (n == 0) y <- func(x) else if (n == 1) y <- func(x,

I'm looking for an R equivalent of Beaton's (1964) Sweep algorithim for partial inversion of a matrix by pivoting. It implemented in SAS/IML as sweep(matrix, indices), described here http://support.sas.com/documentation/cdl/en/imlug/59656/HTML/default/langref_sect266.htm and here for python http://adorio-research.org/wordpress/?p=262 -- Michael Friendly Email: friendly AT yorku

Hi, Quick question on reading data. I am running simulations but want to allow the user the option to define the number of simulations. How can I have R read-in user data entered from the keyboard? Is there a difference for reading in numeric and character data? For example, I am trying to write the following in R: Enter Number of Iterations? <<<the user then enters a number say Y

Thank you for providing the example code... for the request of running it multiple times it would have helped if you could have confirmed that the example ran through without errors... there were a lot of mistakes in it. Look into using the reprex package to check your example next time. I don't do this kind of analysis... I really don't know what to expect from the functions. The

That would be a *really* bad idea. See the l0phtcrack source for details :-). Seriously, though. The password hashes used on NT are very poor. They don't use salt and people are now

Even though I work with R since a year or so I still struggle with simple problems. I hope someone can help me with this. Been trying for days and am a little frustrated now.
