ggplot2 - R/ggplot error: too large for hashing -


I am plotting a time series graph using ggplot, however whenever the size of the data frame is more than 600 , Ggplot throws the following error:

Any errors. Error in default (brake): Length 1136073601 is too large for hashing

In fact It has just given me a single error when I try to plot 400 items.

To plot these things My code for is based on:

  qplot (time, value, data = test3, geom = "line", group = variable) + facet_grid (variable ~., Scale = "free_y ")   

Any sign and I will be very grateful!

I'm using this to massage the date mentioned from the date:

  test $ time & lt; - StripTime (test $ time, format = "% Y-% m-% d% H:% M:% S") test $ time & lt; - as.POSIXct (test $ time, format = "% H:% M: (test $ time) " [1] "POSIXt" "POSIXct" "  

class < Code>

Set a timezone explicitly in calls. POSIXct (), like
