Plotting x-axis labels perpendicular to the axis
Hi, The following command: axis(1, at= 1:50, labels= sampleNames(data)) produces an X-axis with 50 ticks and labels drawn from the sampleNames namespace. Problem is the labels at each tick are printed parallel to the x-axis and thus run into each other. How do I specify for the labels to be printed perpendicular to the x-axis? Thanks in advance.

Methods to explore R data structures
...ss() to see what the object is. str() / attributes() to probe inside the object, and something@something$something to walk it and explore. Is there any other way? Also, without reading documentations, is there a way to know what functions are available to extract data from it? For example, there is sampleNames() which works on ExpressionSet and AnnotatedDataFrame (which is a part of ExpressionSet). How do I know they are available (as sometimes I can't recall where I've seen them and I forgot the function names). And what are R functions? Are those two separate functions or polymorphic functions?...
