Hi there, this is a very easy question, i just cant seem to find a straight answer- i need this one thing, then i can finish my project for this term. I am making an interactive application with R where I get the user to input numbers that the program then uses in the analysis. I have figured out a lot of stuff, yet this is somehow hard to find the answer to: #-------------------------------------------------- defineSamples<- function() { ANSWER<-numeric() ANSWER<-readline("enter the number of groups: ") } runit() ANSWER # this does not hold the value the user inputs #------------------------------------------------- If I then see what ANSWER is storing it says "numeric(0)", how do I get this to store whatever number the user inputs (and am i going to have to convert from a string to a number???

what you want is: defineSamples<- function() { readline("enter the number of groups: ") } ANSWER <- defineSamples() On 4/1/07, projection83 <mkurowski@gmail.com> wrote:> > > Hi there, this is a very easy question, i just cant seem to find a > straight > answer- i need this one thing, then i can finish my project for this term. > > I am making an interactive application with R where I get the user to > input > numbers that the program then uses in the analysis.

I dont know if thats what i want (its not working like i want). I would like to have R pause, wait for a user input of a number, then store that number as a variable to use in the next calculation it does... Or should the below do that? jim holtman wrote:> > what you want is: > > defineSamples<- function() > { > readline("enter the number of groups: ") > } > > ANSWER <- defineSamples() > > > > On 4/1/07, projection83 <mkurowski at gmail.com> wrote: >> >> >> Hi there, this is a very easy question, i just cant seem to find a >> straight >> answer- i need this one thing, then i can finish my project for this >> term. >> >> I am making an interactive application with R where I get the user to >> input >> numbers that the program then uses in the analysis.
