hi chaps:
* I have some suggestion, the first of which is about suggestions, R tells me who the contributors() are, but this should also tell me where I should email suggestions to. Is it this mailing address/list? a repository of suggestions? an individual?
this came up because i wanted to suggest enhancements:
* the first is for the summary() method for plain data frames. it would seem to me that the number of "NA" observations should be printed as an integer, not necessarily in scientific notation. I have also yet to determine when summary() likes to give means and when it does not. (maybe it was an older version that sometimes did not give means). summary does not seem to have optional parameters to specify what statistics I would like. this could be useful, too.
* another small enhancement: there are four elementary data frame operations that bedevil novices, so they really should have named function wrappers:
delrow( dataframe d, index=45);
insrow( dataframe d, (row)vector v);
delcol( dataframe d, "name");
inscol( dataframe d, (col)vector v);Even a simple alias would do (maybe named row.delete, column.delete). I looked at my R "bible" (venables&ripley), too, but here too it is not as clear as it needs to be. yes, these operations are programmable, but it ain't as obvious as it should be for beginners. these are elementary.
* Finally, a more complex question: I have a historical rate of stock return series (yes, I teach finance). I would like to make a ts plot on the left (plot(date,returns,type="h")), and a plot(density(returns)) on the right. works nicely with par(mfrow=c(1,2)), but it would be even nicer if I could rotate the density plot 90 degrees, so that it is more apparent that the density plot is an aggregation of the points at the same y coordinates. (if need be, a histogram could replace the density plot.) Is it possible to rotate an entire subpanel figure. if there was a "horizontal" parameter to ps.options for plot(), it would do the trick, but this does not work. So, this may be a suggestion, too.
regards,
/iaw
