I want to make some graphics to analyze Covid-19 with ggplot and hrbrthemes in R Google Colaboratory. But, when load the hrbrthemes package, I found the error like this
Error in library(hrbrthemes): there is no package called ‘hrbrthemes’
Traceback:
1. library(hrbrthemes)
Before I face this error, I have loaded ggplot2 and hrbrthemes package just like this
library(ggplot2)
library(hrbrthemes)
How I solved this? Can one of you help me to solve this problem? I'm very pleased when you can find the solution for me. Thank you ^^
