* summary.formula: fixed problem with deparse formula. Thanks: Andreas Kiermeier
* describe: added relative information measure for numeric variables  a measure of how continuous the variable is

* DESCRIPTION, NAMESPACE: multiple function changes to work in Rdevel
Changes in version 3.144 (20140413)
* rcspline.eval: stop new logic for ignoring outer values when there are many ties when there are also many ties on interior values. Added new logic to use interior unique values of x when the number of unique x is small.
* latexBuild: generalized with insert argument
* latex.default: modified to use mods of latexBuild, fixed bug with caption.loc='bottom' (thanks: YacineH)
* latex.default: fixed bug where comma did not appear after caption={} for ctable (thanks: Johannes Hofrichter)
* tests: fit.mult.impute.bootstrap.r: added new example (thanks: Jane Cook)
* fit.mult.impute: added call for fit.mult.impute in returned object, replacing call from fitter; makes update work for fit.mult.impute
* summary.formula: fixed recognition of multiple lefthandside variables to trigger call to summaryM (thanks: Kevin Thorpe)
* summaryM: changed group label to '' instead of 0 for formulas like age + sex ~ 1
* Ecdf: added what argument to all functions
* nobsY: return constructed id vector
* addMarginal: instead of .marginal. being logical, make it contain names of variables being marginalized over
* mChoice.c: fixed some inconsistencies
Changes in version 3.143 (20140302)
* format.df: clarified in help file that col.just can contain specifications other than l,r,c, e.g., "p{3in}" to get paragraph formatting in a column. Thanks: Ben Bolker
* latex.default: added example for the above in tests
* label.Surv: got units from inputAttributes in addition, and added type argument
Changes in version 3.142 (20140226)

Changes in version 3.141 (20140225)
* Added latexNeedle function
* Change latexTherm, latexNeedle to use user LaTeX macro \tooltipn to do the popup

* plot.summaryP: omit tick marks for proportion > 1.0
* format.df (used by latex): fixed na.blank logic for character var
* latex: removed newlines when ending environments, added hyperref argument

* Removed recode, existsFunction functions, under.unix object, survfitKM, functions used only by SPlus: comment, mem, mulbar.chart, p.sunflowers
* as.category, is.category, untangle.special: removed
* Removed reference to .R. from many functions
* Remove oldClass, oldUnclass, getFunction
* latex.default: changed 'rotate' to 'sideways' for ctable mode. Thanks: Simon Zehnder <szehnder@unibonn.de>
* gView: removed
* ldBands: removed
* summaryP: new function  graphical replacement for tables of proportions
* ynbind: new function for combining related yes/no variables into a matrix with a label
* added file argument to prn
* summaryP: added autoarrange
* added addMarginal and nobsY functions
* pBlock: new function for blocking variables for summaryP
* summaryP: changed text positioning to grid absolutes, added text.at argument
* scat1d, histSpike: if grid used and y has grid units, fixed logic for frac
* plsmo, panel.plsmo: added scat1d.opts argument
* label.Surv, units.Surv: added, removed ::: in survival calls
* summarize: added keepcolnames argument
* Suppressed startup message unless options(Hverbose=TRUE) is set

* summaryD: added ylab argument
* dotchart3: quit letting left margin be less than preexisting one
* multLines: new function
* Improved nobsY to respect subject IDs when counting number of subjects, and to return an attribute 'formula' without id variable; changed bpplotM, summaryP, summaryS to use this
* Removed nobsY calculations from bpplotM, summaryP, summaryS, enhanced nobsY to allow stratification by treatment
* panel.bpplot: added violin and violin.opts arguments
* summaryS: added medvPanel support duringplot vertical violin plots
