[R] error message no lines available in input

[Katrin Heimann]

Dear all,
a program that worked well for weeks today gave me consistently the error
message

no lines available in input

referring to the lines

for (i in (0:(timeintervals-1)))
{ j=subjectquantity+6+i*(subjectquantity+7)
	print (j)
	results<-read.table(file, header=F, skip=j, nrows=subjectquantity)

timeintervals have been specified as argument as 12
subjectquantity as 9

the file it should be reading starts like:


davide.jtfbase
elena.jtfbase
fabio.jtfbase
francesco.jtfbase
giulia.jtfbase
kerstin.jtfbase
Lucia.jtfbase
maria.jtfbase
Stephanomer.jtfbase
