Changelog

Allow factor variables in pre-factor, factor, and attribute based maps. Correlations will be calculated polycor::hetcor and factor scores are calculated using psych::score.irt.poly.
Add option to save cluster membership for hierarchical clustering
Add gower distance as a distance metric for hierarchical clustering
Use patchwork for grouping multiple plots together
Update action buttons that initiate model estimation when one or more inputs are changed. When a model should be re-estimated, a spinning “refresh” icon will be shown

Documentation updates (i.e., key functions for each tool)
Numerous small code changes to support enhanced auto-completion, tooltips, and annotations in shinyAce 0.4.1

Label numbers for stored factor scores from factor analysis will now always correspond to the numbers used in the summary output
Fix for kmeans bar-plot after dplyr 0.8.1 release
Add information on R-squared when storing PW and IW tables for conjoint analysis with individual level data
Added option to (not) standardize data for K-clustering or Hierarchical clustering.

Ensure variable and dataset names are valid for R (i.e., no spaces or symbols), “fixing” the input as needed
Fix initial plot size for kclus in the browser interface
Fix labels in pre_factor after a ggplot2 update
Avoid a warning in the pre_factor Plot tab on refresh
Option to pass additional arguments to shiny::runApp when starting radiant such as the port to use. For example, radiant.multivariate::radiant.multivariate(“https://github.com/radiant-rstats/docs/raw/gh-pages/examples/demo-dvd-rnd.state.rda”, port = 8080)
Avoid generatign pred_data = "" for conjoint predictions
Load a state file on startup by providing a (relative) file path or a url

Major changes

Option to add selected labels to the dendogram in hierarchical clustering
Replace non-ASCII characters in example datasets
Remove rstudioapi as a direct import
Revert from svg to png for plots in _Report > Rmd_ and _Report > R_.svg` scatter plots with many point get to big for practical use on servers that have to transfer images to a local browser
Removed dependency on methods package

Various changes to the code to accomodate the use of shiny::makeReactiveBinding. The advantage is that the code generated for Report > Rmd and Report > R will no longer have to use r_data to store and access data. This means that code generated and used in the Radiant browser interface will be directly usable without the browser interface as well.
Used ggplot2 and ggrepel for mds brand maps
Used ggplot2 and ggrepel for prmap brand maps

Renamed pmap function for perceptual maps to prmap to avoid conflict with purrr::pmap
Estimate buttons indicate when models should be re-estimated based on changes in user input
Upload and download data using the Rstudio file browser. Allows using relative paths to files (e.g., data or images inside an Rstudio project)
Long lines of code generated for Report > Rmd or Report > R will be wrapped to enhance readability

Updated output formatting code to make coefficient information more easily accessible
Add KMO measures for individual variables to Factor > Pre-factor
Code cleanup
