I just started R for the first time in a while and got an error message when importing the xml2 and other packages into R. 

install.packages("xml2")
library(xml2)
result <- read_xml("IE0216C.xml")

That is all I´ve been doing and I get these two messages: 

The downloaded binary packages are in
    C:\Users\alex-\AppData\Local\Temp\Rtmp0OcyfG\downloaded_packages
Error in loadNamespace(name) : there is no package called ‘yaml’
Error in loadNamespace(name) : there is no package called ‘yaml’
Error in loadNamespace(name) : there is no package called ‘yaml’
Error in loadNamespace(name) : there is no package called ‘yaml’
> library(xml2)
Error: package or namespace load failed for ‘xml2’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package named 'Rcpp'

I worked with R for quite a while last year and never got this erro, I´d appreciate a lot if someone could help me ou.

best, Alex

    please read the output of `install.packages('yaml')` _very_ carefully -- it's likely it failed to install for some reason and the output will give you a hint as to why – MichaelChirico Mar 10 '20 at 13:48
  • Thanks a lot for your quick response. I installed yaml separately and did not get any error messages but R tells me that the read_xml function does still not exist. – A. Marx Mar 10 '20 at 14:35
  • repeat this process for `install.packages('xml2')` :) – MichaelChirico Mar 10 '20 at 14:41
