I am using the package ggOceanMaps (and associated ggOceanMapsData) in R to make some maps with bathymetry. For some reason, no matter how I code/plot these, the degree symbol is not showing up on my plots. I am getting a weird square symbol instead.

#install 
#devtools::install_github("MikkoVihtakari/ggOceanMapsData")


#library
library(ggOceanMapsData)
library(ggOceanMaps)

basemap(limits = c(100, 160, -20, 30), bathymetry = TRUE)

The plot I get enter image description here

Any ideas of what might be going wrong? When I try plotting it with my data/other regions I get the same issue. I have updated and restarted r and no luck.

In case this is helpful...

    packageVersion("ggOceanMaps")

 ‘1.3.4’

    packageVersion("ggOceanMapsData")

 ‘1.4’

I was able to find an alternative to be able to include degree symbols following Jaap's answer, but still curious why ggOceanMaps is not working.

  • This appears to be some sort of symbol problem introduced by a 4.2.2 version of R. See https://stackoverflow.com/questions/74940708/degree-symbol-in-plot-r-with-ggplot2-using-rstudio. Uncertain whether it has been fixed in newer R releases. – Mikko Jun 30 '23 at 11:02

    @Mikko Thanks for following up! I didn't think of downgrading the R version at the time. I just re-tried using R version 4.3.1 and degree symbols are working now. – FishyFishies Jun 30 '23 at 11:12

    Good to hear. Thanks for reporting! One worry less :) – Mikko Jun 30 '23 at 12:36
