What's Changed

• Develop by @sestelo in #5

Full Changelog: v1.5.0...v1.5.2

• new implementation in R of the allotest. Now it is possible
  to choose between two statistic test: "res" (based on residuals on the
  null model) or "lrt" (based on the likelihood ratio test using rss0 and rss1).

• the localtest function has a new argument: ci.level.

• fixed some bugs in the formula argument of frfast, globaltest, localtest and allotest functions.

• the plotting functions have been changed. Users can choose between the plot.frfast function, used for base graphics, and the autoplot.frfast function, which is appropriate for ggplot2-type plot and returns objects of the ggplot class.
• we have merged the plottdiff function of the previous version of the package with plot.frfast and with autoplot.frfast by means of the new argument diffwith. This new argument lets users visualize the differences between two factor’s levels.

The argument smooth has been incorporated to the functions. Users can select now the type of smoother: kernel (by default) or splines.

• corrected bug at globaltest function (random numbers problem)

• the random numbers generation (for the bootstrap) has been changed reducing the computational time.
• the plots are now obtained by means of the ggplot2.

• the srand function of the fortran code has been deleted. Now it call the R one.
