gganimate and ffmpeg

=> Try to install gganimate in CoLab, it is unavailable. 

=> try in RStudio, 

File access error: 

Warning: file_renderer failed to copy frames to the destination directory  

file_renderer(dir = ".", prefix = "gganim_plot", overwrite = FALSE)

The frame sources:

/var/folders/bw/k6_tkc2142v1wh5r_1yhkqhc0000gp/T//RtmpIopU0P/1eec3399c50d/gganim_plot0001.png

I tried to change file permission in Finder, but my username is not allowed. 

The following codes worked: 

file_renderer(dir = "/Users/hqin/github/R-animation-sandbox/tmp/", prefix = "gganim_plot", overwrite = TRUE)
anim <- p + transition_time(year) +
  labs(title = "Year: {frame_time}")
gganimate::animate( anim, renderer=ffmpeg_renderer())

I tested and found out that I have ffmpeg installed.

cointegration project, Rt ~ Google workplace

2022-02-08:  

on ridgeside: Try cajo on Rt ~ G only. 

conda activate /home/hqin/.conda/envs/r2021nov

14:50 $bash commands_cajo-RtG.txt  #this ca.jo on Rt ~ workplace mobility. 

I had to close many sh tabs, and restart the shells. 

15:16 $bash commands_cajo-RtG.txt   #this runs for a while. 

outputfile:  filename = paste( "_autocajo_RtG", start, '-', end, ".csv", sep='')

Somehow, the output file has a wrong start and end labels. 

15:40-7, batch run from 1 to 3151, done in 7 minutes for Rt ~ G. 

 change output file name to _autocajo_RtG1-3151_ridgeside.csv

this is a full-time series co-integration analysis.
