Bug fix for handling of ordered factor and testing of 1xM tables

tableone 0.6.2 (2014-06-01)

BUG FIXES

• The testing of 1 x m table was problematic when a categorical
  variable only have one level. chisq.test() returns Chi-squared
  test for given probabilities (test for strata imbalance) in such
  cases. In this version, testing a 1 x m table always return NA,
  as test for a cross table is not defined in this context.
• Special thanks to Atsushi Shiraishi for reporting this issues.
• Unit testing with the testthat package was added for some
  functions. Thus, the testthat package was added as a suggested
  package.
• The algorithm CreateCatTable used to detect variables to convert
  to factos had a bug. CreateCatTable was effectively (re-)converting
  all variables to factors, which deleted empty levels from factors
  and ordered factors.
• Special thanks to Atsushi Shiraishi for reporting this issues.

printToggle for ShowRegTable and vars omission for CreateTableOne added

tableone 0.6.0 (2014-05-31)

NEW FEATURES

• The CreateTableOne function automatically use all variables in the data frame given to the data argument, if the vars argument is empty.
• The printToggle argument added to ShowRegTable().

noSpaces option added.

tableone 0.5.0 (2014-04-14)

NEW FEATURES

• The noSpaces argument was added to print.* functions. This allows
  removal of spaces added for alignment using fixed-width fonts.
  Use this option if you prefer to align your table in other software.

showAllLevels argument added to print.TableOne()

tableone 0.4.0 (2014-03-30)

NEW FEATURES

• The showAllLevels argument to show all levels of categorical variables regardless of numbers of levels was added to print.TableOne. Previously, it was only available in print.CatTable. To accommodate this feature, insertLevel argument to insert an empty level column was added to print.ContTable.

bug fix release that can handle ordered factors as categorical variables.

tableone 0.3.5 (2014-03-07)

BUG FIXES

• Added more robust class assessment in CreateTableOne and CreateCatTable, which now handles ordered factors correctly. CreateTableOne also drops Surv object for safety.
• "Dropped due to unsupported class" message has been fixed to show variable names with spaces in between.
• This version will be pushed to CRAN in a week. For the time being please install from the github as follows.

## Install devtools (if you do not have it already)
> install.packages("devtools")
## Load devtools
> library(devtools)
## Install directly from github (develop branch)

Bug fix release with better handling of all NA/NaN vectors

tableone 0.3.4 (2014-03-04)

BUG FIXES

• Added the Create* functions handling of all NA/NaN variables. These invalid variables are examined at the beginning and dropped with warning for safety.
• For the strata argument, variables with only one level is dropped with warning because these are meaningless, and caused data handling problems.

Bug fix release with better handling of characters and logicals

tableone 0.3.3 (2014-02-22)

BUG FIXES

CreateTableOne now handles logical and chracter vectors correctly. They are handled as categorical variables, and passed to the CreateCatTable function. Variables that are none of numeric, integer, factor, logical, or character are dropped for safety.

Package description fixed for clarity

tableone 0.3.2 (2014-02-18)

BUG FIXES

• DESCRIPTION changed for clarity. No functional changes.

Bug fix release to be consistent recent NAMESPACE conventions. Resubmitted to CRAN.

tableone 0.3.1 (2014-02-18)

BUG FIXES

• NAMESPACE now includes import(e1071) and import(gmodels).
• DESCRIPTION now includes Imports e1071, gmodels and Suggests survival, instead of Depends...
