• Embed interactive maps into transport regions of UK vignette

Map style similar to Greta's vignette

Run into issue:

Error in select(., geometry) : could not find function select

Whilst running:

{r}
# Set our tmap package mode to _interactive_ to create interactive plots
tmap::tmap_mode('view') # After this call all qtm plots will be interactive 


{r}
# Here we create the  interactive plots
regions_lad %>% select(geometry) %>% tmap::qtm()

Which is fixed in this stack overflow thread:

I had the same issue and it was caused by name clash with another package. Use: dplyr::select to specify the package.

I had forgotten to import library(dplyr) so this is no surprise - the both this and the above approach fix this error.

But, now have error:

Error: Shape contains invalid polygons. Please fix it or set tmap_options(check.and.fix = TRUE) and return the plot

Which appears to be a common issue (571, 577 ) which seems to be due to Simple Features (sf) changes and is fixable with the following:

sf::sf_use_s2(FALSE)

which fixes all errors and allows the .Rmd to knit

However - I'm not too sure this shoulf have fixed the issue?

It seem from @Robinlovelace expereince this issue was occuring when geometries were all valid according to sf::st_is_valid() which (In Robin's instance) returned

summary(sf::st_is_valid(z))
#>    Mode    TRUE 
#> logical      74

However for the joined Loacal Authority Disticts file it seems there is an incorrect geometry:

> summary(sf::st_is_valid(regions_lad))
#>   Mode   FALSE    TRUE 
#>   logical       1     373 

Going to see if I can identify the broken geometry and remove it from the plot and see if it works without the sf::sf_use_s2(use_s2 = FLASE)
I don't understand why it would be plotting even with a broken geometry as I have not called for tmap to automatically fix geometries (i.e. tmap_options(check.and.fix = TRUE))

Not sure what is going on but sf::sf_use_s2(FALSE) is a reasonable fix.
