Text of the page (random words):
mode indented text this file ideas txt is to be maintained as plain ascii for expedience it contains brief sketches of items that might be considered for inclusion in r and provides a spot for adding comments and elaborating on earlier ideas the r ideas list dream dream dream the everly brothers 3d graphics it would be nice to have something more sophisticated than persp for plotting surfaces it would be nice to have contour labels and labels on persp plots first dynamic graphics statistics for the video game generation we need to move to an event based model for this gam models the basic code is at statlib however this is unreliable code also under s and we might want to start from scratch gu s gss looks like a good alternative mapping we have the becker wilks sources for constructing map data bases all we really need is the drawing code data entry current version is quite primitive need at least better factor entry mechanism and the ability to delete rows and columns in the tcl tk world it looks very tempting to try a reimplementation using the table widget menu system some way of adding user definable menus graphapp gnome and tcl tk all point in that general direction the tcl tk stubs are in place but we need an overall plan would it suffice to have a free floating toolbar mechanism or do we want to reinvent the console and have an integrated window top toolbar data files file reading we might want a mechanism for reading ragged files i e with varying number of fields per line excel exports those read table fill na t some advanced method for generating data frames from input files one idea is to elaborate on the fact that when data loads a r file it changes to the data directory and quite flexible input specs can be obtained by having the r file contain xxx rsp file is a specification for txt with a little bit of thought one might avoid the ugliness of the transform and read table calls foreign database formats www wotsit org should rdata be renamed to something user visible xml formula based interfaces the interfaces to various standard tests are inconsistent e g wilcox test takes two vectors but kruskal test a vector and a grouping factor we probably want to keep this for compatibility with s plus but we d like to have a consistent interface using model formulas too this also includes looking at plot formula which has trouble with pch vector and making sure that there s also points formula etc kurt peter plan to work on this misc some very petite stuff can go in here bug report dumps user into vi which he might not know better summaries of multi df effects extend summary lm successive diffs contrast mass has contr sdif choleski with pivoting change defaults for x11 pointsize and the scaling for multiframe layouts add buildinfo tags to package descriptions
