ggfortify is a (nonstandard) contributed package. Please note that per the posting guide linked below:
"For questions about functions in standard packages distributed with R (see the FAQ Add-on packages in R <https://cran.r-project.org/doc/FAQ/R-FAQ.html#Add-on-packages-in-R>), ask questions on R-help. If the question relates to a *contributed package* , e.g., one downloaded from CRAN, try contacting the package maintainer first. You can also use find("functionname") and packageDescription("packagename") to find this information. *Only* send such questions to R-help or R-devel if you get no reply or need further assistance. This applies to both requests for help and to bug reports." So while you may get help here, the above may be a better course of action. Also, if all you have done is copy and paste code, you should consider going through the vignettes for the package. They seem fairly extensive from my quick look and may well provide the answers you seek.
