Hello everyone,
I have a question as to what code should be used if 
one wanted to subset from a dataframe of 7000rows by 38
columns.For example if you wanted to generate a array of 
100 by 38 would you not use the following:
Z<-(dat,dim=c(100,38))
where dat is the dataframe of 7000by 38
Whenever I do this and type show(Z) I get a output of 100 by 38
they all say "integer,7000" as every element of the array.I do not 
understand what is wrong as the printout should have the values from 
the dat file.?
Any help would be appreciated
Paul
