Putting a curl command into a R script and capturing the output to a variable-CodePudding

I would need to use the following bash command (or equivalent) into a R script. ideally, I would need to capture the output into a variable

curl -LH "Accept: text/bibliography; style=bibtex" https://doi.org/10.1002/cbin.11105

I checked the httr library, but I had no luck. Also, I tried to embed the command into a system call, but I was getting a hard to parse output using the option "intern = TRUE". Thanks in advance

CodePudding user response：

library(httr)
res <- GET("https://doi.org/10.1002/cbin.11105", accept("text/bibliography; style=bibtex"))
