reading data rows
I have problems reading a file with more than one row
to carry out mathematical calculations
I have a a file of the form
mu1 mu2 alpha beta Wsigma sigmaA b r
25 15 .05 .05 22 3 .3 .5
30 20 .1 .2 22 .3 .3 .5
I intend to read one row , carry out the calculations
and then the next row with which I intend to do the
same calculations.
I do the following.
p<-read.table(file="eingabe.csv", header=TRUE,sep=";")
data.frame(...

Thanks again for your help.

#Define the Models
#Two simple linear models:
#Model A: respA = a0 + a1x + e(a), e(a) ~N(0, sigma^2(a))
#Model B: respB = b0 + b1x + e(b), e(b) ~N(0, sigma^2(b))
a0= 0; a1 = 1.5; sigmaA=4; b0=50; b1=-2; sigmaB=4; n=250; min=0; max=50;
#Generate Data from the Models
x1 = runif(n, min, max); #Explanatory variable
eA = rnorm(n, 0, sigmaA); eB = rnorm(n, 0, sigmaB);
respA = a0 +a1*x1 + eA; respB = b0 +b1*x1 + eB; #Responses
#K-Means Clustering
resp1 = c(respA, respB);#Put re...
