I am trying to compare and contrast the smoothing in the {mgcv} version
of gam vs. the {gam} version of gam but I get a strange side effects
when I try to alternate calls to these routines, even though I detach
and unload namespaces.
Specifically when I start up R the following code runs successfully
until the last line i.e. plot(g4,se=TRUE) when I get "Error in
dim(data) <- dim : attempt to set an attribute on NULL". On subsequent
attempts to plot any gam::gam object I get the same result. The only
way I can get gam:gam working again is to close down R and restart it.
x=runif(1:20)
y=runif(1:20)
library(gam)
g1= gam::gam( y ~ s(x,5) )
plot(g1,se=TRUE)
detach(package:gam,unload=TRUE)
detach(package:splines,unload=TRUE)
library(gam)
g2= gam::gam( y ~ s(x,5) )
plot(g2,se=TRUE)
detach(package:gam,unload=TRUE)
detach(package:splines,unload=TRUE)
library(mgcv)
g3 = mgcv::gam( y ~ s(x) )
plot(g3)
detach(package:mgcv,unload=TRUE)
library(gam)
g4= gam::gam( y ~ s(x,5) )
plot(g4,se=TRUE)
