Hi I have a problem with converting a matrics in R R has almost the same syntaxes as S-PLUS have so I have also tried to use the manual for that software. My problem is that i have read data in from a database through a RODBC connection and this data is not represented in the right form. The data I have read in, is represented as productnumber in first collumn, weeknumber in the second and a messurment in the third. I want to represent the data as productnumber downwards(rows) and weeknumber horisontally(collumns) and the vallue of the cells should be the messurment. I have looked at a function called "reshapeWide" which I thoght wold handle such a problem but I only get an error message. I have tried to convert the the data when the data was both original and wen converted to dataframe. Do sombody else now about other functions which can be used?. Do I have to make a new function (programming in R)? Thank you in advance Morten -------------- next part -------------- An HTML attachment was scrubbed...
