r - How to specify path to custom package without whole path name on install -

i can't figure out issue here.

i have created package , trying make sure written etc.

to using 'goodpractice' package. run follows:

gp("mypackager") 

and says:

preparing: covr error: `path` invalid: mypackager in addition: warning message: in normalizepath(path) : path[1]="mypackager": no such file or directory 

so run as:

gp("~/r/x86_64-pc-linux-gnu-library/3.4/mypackager") 

and runs time when gets tests folder in specify file path follows: load(file="./data/pathdataframefinal.rda") again trips error:

cannot open compressed file './data/pathdataframefinal.rda', probable reason 'no such file or directory' 

i think must problem file path of package , filepath can specify package name without absolute path of location. how can that?

the getwd() "/home/rstudio/mypackager"
