Hello, I was simply doing a graph, but an error repeatdly occurs. Any idea why? (this only happens in the latest R version, I am a windows user).
What version is that exactly? Please give the output of sessionInfo(), since "the latest R version" means different things to different people.
Thank you, Marta library(Hmisc)
example(xYplot)
xYplot> d <- expand.grid(x = seq(0, 2 * pi, length = 150),
p = 1:3, shift = c(0, pi))
xYplot> xYplot(sin(x + shift)^p ~ x | shift, groups = p, data = d,
type = "l")
Loading required package: grid
Error in xyplot.formula(formula = sin(x + shift)^p ~ x | shift, data =
list( :
argument "x" is missing, with no default
And what made you come to the conclusion that this is a bug in R? In this case, I'm pretty sure your version of Hmisc is an old one. Run update.packages() and try again. -Deepayan
