Thanks. install.packages("devtools") fixed the problem. I have new issues "checking."
Issue 1: I have three functions.
trial2(63, 34, 22, 44, 40, 14) WORKS
Saving theta, t0, t1, t2, t3, ul0, ul1, ul2, ul3, xl0, xl1, xl2, xl3, h0, h1, h2, h3, uf0, uf1, uf2, uf3, xf0, xf1, xf2, xf3 as sysdata.rda to /Users/PJO/Desktop/CF/R
v1plot2(xlim, ylim) WORKS
Saving theta, t0, t1, t2, t3, ul0, ul1, ul2, ul3, xl0, xl1, xl2, xl3, h0, h1, h2, h3, uf0, uf1, uf2, uf3, xf0, xf1, xf2, xf3, tseq, xseq, useq, hseq as sysdata.rda to /Users/PJO/Desktop/CF/R
vfline2(xlim, ylim) HAS WORKED BUT IT NO LONGER WORKS
Called from: vfline2(xlim, ylim)

Error: object 'xseq' not found
Issue 2: I am not sure the following is related to NOT Finding 'xseq'.
I am finding conflicting instructions.
checking Rd \usage sections ... WARNING
Check gives:
Documented arguments not in \usage in documentation object 'trial2':
‘theta’ ‘t0’ ‘t1’ ‘t2’ ‘ul0’ ‘ul1’, ‘xf3’ ‘tseq’ ‘useq’ ‘hseq’ ‘xseq’
Functions with \usage entries need to have the appropriate \alias
entries, and all their arguments documented.
These values, ‘theta’ ‘t0’ ‘t1’ ..., are 'internal data," which I don't have to be documented.
"Objects in R/sysdata.rda are not exported (they shouldn’t be), so they don’t need to be documented. They’re only available inside your package."
