## Ggplot2 Error Bars

So I've a dataframe like this : group N val sd se ci 1 206 3 37.2269533 7.9688645 4.6008261 19.7957568 2 207 3 2.0731505 2.2843009 1.3188417 5.6745180 3 208 3 2.2965978 See ?geom_bar for examples. (Deprecated; last used in version 0.9.2) So anyone knows how to resolve that ? If you want y to represent values in the data, use stat="identity".

A useful cheat sheet on commonly used functions can be downloaded here. to specify the desired confidence interval, but the default is 0.95 so it really wasn't necessary in this example. Finally, this approach lends itself to the use of many built-in functions for generating confidence limits with more statistical rigor.
