This issue occurs only when both the evd and ismev packages are loaded.
 Please retract this posting, if possible.  Thank you in advance!

Subject: tcplot documentation in evd package
To: r-help@r-project.org


Hello, and please advise regarding any errors/omissions on my part.
However, the documentation for R's tcplot function in the evd package
appears to contain an error.  I am using evd version 2.2-4 in R 2.14.0
with Windows XP.

> data(portpirie)
> mrlplot(portpirie)  ## No Error

> tlim <- c(3.6, 4.2)

> tcplot(portpirie, tlim) ## Line from documentation
Error in fpot(data, u[1], model = model, cmax = cmax, r = r, ulow =
ulow,  :
 `x' must be a non-empty numeric vector


> tcplot(portpirie, tlim=c(3.6, 4.2)) ## explicitly specifying the
threshold limits
Error in fpot(data, u[1], model = model, cmax = cmax, r = r, ulow =
ulow,  :
 `x' must be a non-empty numeric vector

tcplot(portpirie$SeaLevel, tlim) ## Resolves Issue

gpd.fitrange(portpirie$SeaLevel, 3.6, 4.2) ## An alternative, still
naming the SeaLevel vector

Please advise.  Thanks!

Mike
