Assuming that you are using the xts package, try this:
data(sample_matrix)
sample.xts <- as.xts(sample_matrix)
open <- as.vector(sample.xts[,1])
month <- as.Date(time(sample.xts))
plot(open, month, type="l")

Basically it works, but I use the xts format and the axis are messed up.
plot(c(time(ser)) ~ c(ser), type = "l")
Error in as.POSIXct.default(x) :
do not know how to convert 'x' to class "POSIXlt"
I don't know why do you have any idea?
Besides, why do you use the c(...) function in your code ?
And finally, i am not used to the ~ operator and the R doc did not help me,
could you tell me what it does?
Sorry for all the questions...
