Deducer 0.0-1

• added new data viewer with excel like editing. a variable view is included assist in the editing of variable properties.
• added in variable recoding dialog to Data menu and variable view
• added factor editor to Data menu
• added data.frame sorting dialog and R function to Data menu
• added data.frame merging dialog to Data menu
• added frequency dialog to Analysis menu, which returns variable level frequencies
• added descriptives dialog to Analysis menu, which creates common descriptive statistic tables including mean, minimum, maximum, standard deviation, skew and kurtosis. Custom statistics can also be included easily within the gui or in the console. Descriptives can also be stratified by any number of variables.
• Added Contingency tables dialog, along with support R functions. Prints out contingency tables in a pretty format, along with cell statistics such as expected counts, residuals, standardized residuals, adjusted standardized residuals, row %, column % and cell total %. Stratification by a separate variable is supported.Various statistical tests and effect sizes are implemented, including the chi-squared, likelihood ratio, Fisher's exact, Kruskal-Wallis, and Mantel-Haenszel tests along with the Cramer's V, Kendall's Tau, and Spearman's Rho measures of effect size. Monte Carlo simulated tests are available for the Chi-squared and Fisher's exact tests. Mid p-values are implemented for Monte Carlo and exact tests.
• Added data.frame subset dialog.
• Added Two sample tests. Currently implements the t-test, ks.test, wilcoxon, resampling (permutation), and the brunner-munzel test. Functions for pretty printing are provided which make the application of these tests to multiple variables much more visibly appealing.
• Added One sample tests. Currently implements the t-test and the Shapiro-Wilk.
• Added K sample tests. Currently implements ANOVA, Welch ANOVA, and kruskal-wallis.
• Added Correlations. Currently implements Pearson's, Spearman's, and Kendall's.
