help with plotmeans (gplots)
Your data is probably not arranged correctly. See if this works for your data:
# Creating a reproducible example set.seed(42) dat <- matrix(rnorm(100*15, 5, 5)+rep(1:15, each=100), 15, 100,
byrow=TRUE)
str(dat)
num [1:15, 1:100] 12.85 13 -2 8.98 16.67 ...
require(gplots) # Rearranging dat as a data.frame with a time variable (1 to 15)
and the experimental value (val)
# See the result of str(dat2) below for the structure dat2 <- data.frame(time=rep(1:15, each=100),
val=as.vector(t(dat)))
str(dat2)
'data.frame': 1500 obs. of 2 variables: $ time: int 1 1 1 1 1 1 1 1 1 1 ... $ val : num 12.85 3.18 7.82 9.16 8.02 ...
plotmeans(val~time, dat2, n.label=FALSE)

Each experiment lasts for 15 iteration. Thus I have collected results into a data.frame with 100 columns (one column for each experiment) and 15 rows (one row for each iteration). I would like to plot mean values at each iteration using plotmeans, but I am unable to understand the syntax I should use. I tried: times<-as.factor(seq(1,15)) plotmeans(data~times) with no luck... what should I tell to plotmeans in order to evaluate my dataset? Best regards, Simone
