Lab 3 video? + packages error

[CynthiaLteif]

Should we expect to watch a video for lab 3? The second lecture video mentions that there is one but can't seem to find it. @AntJam-Howell

I'm also receiving this error while trying to load the tmap library which is causing an issue.

[AntJam-Howell]

Hi @CynthiaLteif, could you point me to the place that you see the sentence that indicates a video for lab 3? I dont see any mention of video in the course schedule or the lab instructions that mention the need to watch a video. Thank you.

It looks like you will need to manually download the XML package. Best,

[CynthiaLteif]

Yes sure. clusterintro2 lecture video (second lecture video), minute 13:55

Noted, thanks. @AntJam-Howell

[AntJam-Howell]

@CynthiaLteif oh got it, nice catch from the video. Actually, the 3rd video was dropped upon new iteration of the course, so nothing else for you to watch. Thanks!

[CynthiaLteif]

I'm still facing the issue with the tmap library even after manually installing the xml package. I think there is an issue with the downloading the package itself. (check photo below) Are we expected to use this rmd file for lab 04? @AntJam-Howell

[AntJam-Howell]

That is frustrating... Can you try to open a new .R file and enter in option 1 code below. And if that doesn't work execute the codes for option 2.

Option 1

install.packages("tmap")
library("tmap") 

Option 2

install.packages("devtools")
install.packages("remotes")
library(devtools)
library(remotes)
install_github("r-tmap/tmaptools")
install_github("r-tmap/tmap")

library("tmap") 

[AntJam-Howell]

If that doesn't try:

install.packages("tmap", dependencies=FALSE)

[CynthiaLteif]

Option #3 worked (install.packages("tmap", dependencies=FALSE))

Thanks!

[CynthiaLteif]

So sorry to bother you with this but running the code worked fine, however, knitting caused an error:

@AntJam-Howell

[CynthiaLteif]

And when I run all, I get this error for this part of the code @AntJam-Howell

[AntJam-Howell]

Hi Cynthia, You should only install the trap package one time. Try removing that and replacing it with library(tmap)

If I do that the same error message occurs. @AntJam-Howell

[alinemaestas]

I am still have the same issue also. I signed up for the rstudio cloud so that tmap would work, but now it won't knit html files.

[CynthiaLteif]

It's very odd. I haven't been able to make it work since Monday. @alinemaestas

[alinemaestas]

@CynthiaLteif Try updating R and Rstudio. I run it on my mac and when I checked out the latest versions for both, R had a newer version from Oct and Rstudio had a newer version from Sept, I think. Either way, I updated both, installed the packages all over again and installing tmap actually worked this time. I kept getting an error for the Stars dependency and with the updated versions, it installed it right away. So it finally worked. Took about about a total of 4 hours to try to figure out what's wrong, but it took me only 5-10 minutes for the updates. 🤦🏻‍♀️

[AntJam-Howell]

@CynthiaLteif @alinemaestas I went back and also had troubles knitting due to a problem with another package, not tmap. I updated everything and tried to install the package and got it to work again. Definitely frustrating working in a live coding exercise based on earlier versions of packages, and is a problem with open-sourced software like R. Hopefully, updating R, Rstudio and all libraries helps solve others problems as well. keep me posted.

[CynthiaLteif]

I was working with an older version of R. Thanks for pointing it out! tmap finally worked. @alinemaestas @AntJam-Howell but I still can't knit. Fairly confident I did something wrong with the code this time. Here's the error message: Error in as.list.environment(environment()) : object 'bb' not found

Related to this code: tm1 <- tm_shape( sanf_dorling, bbox=bb ) + tm_polygons( col="cluster", palette="Accent" )

tm2 <- tm_shape( sanf_dorling, bbox=bb ) + tm_polygons( col="cluster2", palette="Accent" )

tm3 <- tm_shape( sanf_dorling, bbox=bb ) + tm_polygons( col="cluster3", palette="Accent" )

tmap_arrange( tm1, tm2, tm3 )

The bounding box is the equivalent of xlim and ylim arguments on plots. You’ve got to define one for your map using lat and lon limits.

# user-defined bounding box to move slocer to subjects 
bb <- st_bbox( 
  c( xmin =  -10451823, xmax = -10324525, 
       ymax = 5639769, ymin = 5491665 ), 
               crs = st_crs("+init=epsg:3395"))

Thank you! @lecy
