replace 三千多 with 数千 01-setup.Rmd

希望到你把坑填满的时候不需要改成“万余”

[yihui]

已经是万余了：https://cran.rstudio.com/web/packages/

[dongzhuoer]

干脆践行“文学化编程思想”吧

```{r, include=FALSE}
cran_page = readr::read_lines('https://cran.rstudio.com/web/packages/');
package_number_line = stringr::str_subset(cran_page, 'repository features');
package_number = stringr::str_extract(package_number_line, '\\d+');
```

还有r package_number个用户贡献的附加包

算了，写着玩玩，希望你能在数万之前出版
