ggOceanMaps 包未在纬度和经度值的 x 和 y 轴标签中显示度数符号

Question

我在 R 中使用 ggOceanMaps 包（和关联的 ggOceanMapsData）来制作一些带有测深仪的地图。出于某种原因，无论我如何编码/绘制这些，度数符号都不会出现在我的地块上。相反，我得到了一个奇怪的方形符号。

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


#library
library(ggOceanMapsData)
library(ggOceanMaps)

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

我得到的情节

有什么可能出错的想法吗？当我尝试用我的数据/其他区域绘制它时，我遇到了同样的问题。我已经更新并重新启动 r 但没有运气。

万一这有帮助...

    packageVersion("ggOceanMaps")

 ‘1.3.4’

    packageVersion("ggOceanMapsData")

 ‘1.4’
