no pkg on search list error after update to 0.9.2

[Pierre Roudier]

Hi everyone,

I'm updating one of my packages that makes use of ggplot2 (yup, I'm a wee late),

I'm running on the following error when I try to plot stuff using my package:

> clhs::plot.cLHS_result(res)
Error in as.environment(where) :
no item called "package:ggplot2" on the search list
> traceback()
11: exists(name, "package:ggplot2")
10: find_global(scale_name, env)
9: scales_add_defaults(plot$scales, data, aesthetics, plot$plot_env)
8: get(x, envir = this, inherits = inh)(this, ...)
7: p$compute_aesthetics(d, plot)
6: f(d = data[[i]], p = layers[[i]])
5: dlapply(function(d, p) p$compute_aesthetics(d, plot))
4: ggplot_build(x)
3: print.ggplot(pl[[1]])
2: print(pl[[1]])

[17] scales_0.2.2 sp_0.9-99 stringr_0.6.1 tools_2.15.1

The error disappears if I type library(ggplot2) and run
clhs::plot.cLHS_result(res) again... which is weird as I'm importing
ggplot2 in the NAMESPACE:

[...]

import(utils,
ggplot2,
grid
)

importFrom(scales,
percent
)

importFrom(
plyr,
ddply,
dlply
)

importFrom(
reshape2,
melt
)

[...]

Would anybody have a hint - I guess I'm missing something here.

Cheers,

Pierre

This is a bug in 0.9.2... It happens with packages that import ggplot2
-- in which case ggplot2 is loaded but not attached. We're going to
try to get 0.9.2.1 (which fixes this bug) out quickly.

In the meantime, one workaround is to put require(ggplot2) in your
code so it gets attached. We'll try to keep the list updated on when
it goes through.
