Download GPM-IMERG satellite images in R - r

Question

I've been trying (a lot) to download NASA's GPM-IMERG satellite images with precipitation data from R. I'm doing the question in this forum and not in the GIS forum because I read that most r users are here. (FYI: Im running Windows 10 and r 3.6.3 in rstudio). So far I've tried the following:
Created an account at PMM-NASA (see here). Everything worked well.
Installed the gpm package from devtools::install_github("csaybar/gpm"), followed by
gpm_getaxel() (see here). I tried running the following code.
gpm_download(path = RutaDownloads,
user = "myuser#email.com",
password = "myuser#email.com",
dates = c('2017-01-01','2017-02-28'),
band = 3,
lonMin = 70,
lonMax = 75,
latMin = 34,
latMax = 38,
product = 'finalrun',
quiet = F,
n = 1)
However, it did not worked. The error shown in rstudio is the following.
'gdal_translate' not found Error in gdaltranslate_exist() : GDAL
should be declared as a system variable if you are using Windows
I haven't had any problems running gdal when working with multiple rasters/vectors in R (so far). Does anyone know if I have to install gdal in my PC apart from installing rgdal in r? If so, how can I do it and 'synchronize' it with R to be used with gpm package? I know there is a lot of information in google, however, I'd rather take the advice from anyone that has done this before, because in the past I did not have such a good experience working, for example, with GDAL and Python, and that is the main reason I started working my GIS codes in R.
I also tried with another alternative installing the remotes package and remotes::install_github("bastianmanz/GPM_rain") (See here). However, this uses the rhdf5 package, which is not available for my R version, and thus I installed the BiocManager and then BiocManager::install("rhdf5") (following the instructions from here). With GPM_rain there are two possible ways to download the images: (1) with wget i.e. system_download, but its not straightforward because it needs a list of the files to download, and (2) with rcurl_download using RCurl. This seemed easy to use. Nevertheless, the first problem is that I cannot specify lat/long for the image extent and, as in point 2, it did not work. I tried running the following code:
rcurl_download(product = "nrt",
nrt_type = "late",
start = 20170101,
end = 20170131,
userpwd = "myuser#email.com:myuser#email.com")
But the error says that rcurl_downloadfunction was not found. How to fix any of the above errors or have any other solutions, I would be really grateful if you could share your experience, specially for option 2, where I can set lat/long to download the data. Thanks in advance,
Jorge.

Package gpm is "retired" according to its developer (see here).
