  <dc:description>New Features

vis_compare() for comparing two dataframes of the same dimensions
vis_expect() for visualising where certain values of expectations occur in the data
Added NA colours to vis_expect
Added show_perc arg to vis_expect to show the percentage of expectations that are TRUE. #73

vis_cor to visualise correlations in a dataframe
vis_guess() for displaying the likely type for each cell in a dataframe
Added draft vis_expect to make it easy to look at certain appearances of numbers in your data.
visdat is now under the rOpenSci github repository

Bug Fixes

Fix bug reported in #75 
where vis_dat(diamonds) errored seq_len(nrow(x)) inside internal 
function vis_gather_, used to calculate the row numbers. Using 
mutate(rows = dplyr::row_number()) solved the issue.

Fix bug reported in #72
where vis_miss errored when one column was given to it. This was an issue
with using limits inside scale_x_discrete - which is used to order the
columns of the data. It is not necessary to order one column of data, so I
created an if-else to avoid this step and return the plot early.

Fix visdat x axis alignment when show_perc_col = FALSE - #82

fix visdat x axis alignment - issue 57

fix bug where the column percentage missing would print to be NA when it was exactly equal to 0.1% missing. - issue 62
vis_cor didn't gather variables for plotting appropriately - now fixed
