Rolf: Not sure what "reasonably thorough" means but:
? boxplot says: ... pars a list of (potentially many) more graphical parameters, e.g., boxwex or outpch; these are passed to bxp (if plot is true); for details, see there. Well, that seems pretty clear to me, so I went to ?bxp to find in the pars listing: outlty, outlwd, outpch, outcex, outcol, outbg: outlier line type, line width, point character, point size expansion, color, and background color. The default outlty= "blank" suppresses the lines and outpch=NA suppresses points. It seems to me that this (and other omitted excerpts + examples) is at least a reasonable answer to the query (allowing the reader to at least infer that bxp does not distinguish degrees of outlyingness), so I don't understand your criticism. Feel free to respond privately if you prefer. -- Bert Bert Gunter Genentech Nonclinical Biostatisics -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Rolf Turner Sent: Wednesday, August 19, 2009 1:27 PM To: ottorino-luca.pant...@unifi.it Cc: Rnewbie; ERRE Subject: Re: [R] mild and extreme outliers in boxplot On 20/08/2009, at 3:13 AM, Ottorino-Luca Pantani wrote: > Rnewbie ha scritto: >> dear all, >> >> could somebody tell me how I can plot mild outliers as a circle(°) >> and >> extreme outliers as an asterisk(*) in a box-whisker plot? >> >> Thanks very much in advance >> > ?boxplot > > or > > help(bxp) This is the sort of response that gives R-help a bad name. I had a reasonably thorough look at these help files and saw ***nothing*** that would answer the OP's question. The information may be there --- I'm not sure about this --- but it is far from obvious. Explicit reference to the appropriate lines of the help file(s) would be useful. cheers, Rolf Turner ###################################################################### Attention: This e-mail message is privileged and confidential.
