## I would like help in using variable values in plotmath expressions
## in lattice
x <- 1:10
y <- 1:10
pval <- .95
plot(y ~ x, ## works as I want in base graphics
main=substitute(list(alpha * " = " * group("",list(p),"")),
list(p=pval)))
plot(y ~ x, ## doesn't work as intended: "pval" is displayed
main=substitute(list(alpha * " = " * group("",list(pval),""))))
try( ## doesn't work: object 'alpha' not found
xyplot(y ~ x,
main=substitute(list(alpha * " = " * group("",list(p),"")),
list(p=pval)))
)
xyplot(y ~ x, ## doesn't work as intended: "substitute" is displayed
main=expression(substitute(list(alpha * " = " * group("",list(p),"")),
list(p=pval))))
xyplot(y ~ x, ## doesn't work as intended: "p" is displayed and "pval" is
displayed
main=expression(list(alpha * " = " * group("",list(p),"")),
list(p=pval)))
xyplot(y ~ x, ## doesn't work as intended: "pval" is displayed
main=expression(list(alpha * " = " * group("",list(pval),""))))
Thanks
