Decompress .tif.gz file using R

I got data from Chirps in tif.gz format, I tried R.utils::gunzip to get the maps but I got an error.

file<-"./chirps-v2.0.1981.01.01.tif.gz"
R.utils::gunzip(file,remove=F)

Error:

Error in readBin(inn, what = raw(0L), size = 1L, n = BFR.SIZE) : 
  error reading from the connection
In addition: Warning message:
In readBin(inn, what = raw(0L), size = 1L, n = BFR.SIZE) :
  invalid or incomplete compressed data

data link.

If there is a better alternative to unzip these files it will be a great solution. Thank you in advance.

I tried these but it didn't work R: read GeoTiff from gz file with a connection and raster package Decompress gz file using R

The following works for me:

url <- paste0("https://data.chc.ucsb.edu/products/CHIRPS-2.0/",
              "global_daily/tifs/p05/1981/chirps-v2.0.1981.01.01.tif.gz")
download.file(url, "chirps-v2.0.1981.01.01.tif.gz")
R.utils::gunzip("chirps-v2.0.1981.01.01.tif.gz", remove = FALSE)

File: chirps-v2.0.1981.01.01.tif
