Error in ncol(p_matrix) : could not find function "ncol"

[jules32]

Question from @rroxana10 from the UKI assessment:

unfortunately while the CalculateAll function is running, I get an error when it tries to calculate pressures for each region:
Calculating Pressures for each region...
Error in ncol(p_matrix) : could not find function "ncol"
As usual, I tried to fix it, added the base package again and tried to figure out what is wrong, but I really can't figure it out. I even tried to add up the base library again but it still doesn't work. I have updated the repository with the changes I've made, if you want to take a look.
Do you have any ideas why this error is occuring?

This is actually due to a known issue in the tidyr package. But in the meantime, have improved the affected code in the ohicore package. This fix is currently in the @dev branch of ohicore but you can install that directly from GitHub.
So, you can do the following:

## uninstall ohicore
remove.packages("ohicore") 

## reinstall ohicore from the dev branch: 
source('install_ohicore.R') # note the @dev: `devtools::install_github('ohi-science/ohicore@dev')`

## Calculate Scores
source('calculate_scores.R')
