I tried to install the package, but failed. The R >=3.4 was enforced to be required.

I do not want to move to the recent R version. Is any alternative approach? Thanks in advance.

@zhenyisong RCurl requires 3.0 and is a dependency. I'll lower the requirement to match -- R (>= 3.0). You could test a lower version by downloading or cloning the repository from here, deleting the version requirement in the DESCRIPTION file R (>= 3.0) ==> R and attempting to build and install it.

Here are the R version requirements for dependencies (Imports) and recommended packages (Suggests):

Imports:

• RCurl requires 3.0
• XML requires 2.13
• purrr doesn't have a requirement

Suggests:

• tibble requires 3.1.0
• Rmarkdown requires 3.0
• testthat requires 3.1,
• knitr requires 3.1
• BiocStyle requires 3.0

@mmulvahill thanks. BTW, I did not find the correspondng version in the CRAN ( just curioius about it).

@zhenyisong @smahaffey Turns out this is a Bioconductor requirement. We'll be in the next version of Bioconductor (3.6), so I'm going to re-enforce this requirement.
