A function cannibalized and slightly simplified from http://www.cookbook-r.com/Manipulating_data/Summarizing_data/

1	reportSE(data = NULL, dv, groupvars = NULL, conf.interval = 0.95)

`data`	A data frame in the long format
`dv`	A string indicating the column name of the dependent variable (what is measured, recorded)
`conf.interval`	The rate to use to compute the confident interval. Defaults to .95
`wid`	A string indicating the column name of the subjects (or observations)
`within`	A vector of string of column names of the within variables (repeated within the same observation)
`between`	A vector of string of column names of the between variables (across observations)

The function compute simple descriptive statistics: number of observations (N), mean, standard deviation (sd), confident intervals (ci) and standard error (se).

Return a data frame of the number of observation (N), mean, standard deviation (sd), corrected standard error (se), and confident interval (ci) by conditions.
