Hi Dennis,
It looks like something is wrong about configuration of ggplot dependency with
plyr.Since i saw some threads about this particular error message.
I tried several times by installing different versions of plyr but it did not
work.
========
sampledata= matrix(c(1.002, 1.76, 0.67, 0.99, 1.38, 1.0, 0.5, 0.78,
1.003,0.57, 0.99, 0.58, 0.76, 1.23, 1.45, .78,1.43, 1.34, 1.0, 0.9), ncol = 5,
dimnames = list(c("cond1", "cond2","cond3", "cond4"), c("col1","col2", "col3",
"col4", "col5")))
sdata <- melt(sampledata) # melt method for matrices
sdata$grp <- factor(c('grp1', 'grp1', 'grp2', 'grp3'))
sdata$time <- rep(1:5, each = 4)
library(ggplot2)
h <- ggplot(sdata, aes(time, value))
h + geom_point(aes(colour = cond), size = 2.5) + geom_line(aes(colour = cond),
size = 1)
Error in get("make_aesthetics", env = x, inherits = TRUE)(x, ...) :
could not find function "empty"
