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 [[alternative HTML versi...
