To call in the statistician after the experiment is done may be no
more than asking him to perform a post-mortem examination: he may be
able to say what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does
not ensure that a reasonable answer can be extracted from a given body
of data. ~ John Tukey

> Attached table (that contains summary for a genetic association study) was read using the command:

> test <- read.table('testDat.txt',header=FALSE,stringsAsFactors=FALSE)
>
> Results from the summary of the attached table is provided below:

>> summary(test$V5)
>    Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
>   22070   22070   22070   22070   22070   22070
>
> As we can see column 5 of this table contains only one value - 22072
> I am confused as to why I am getting a value 22070 in the summary of this column.
>
> I tested this using versions of R including - R version 3.2.1 (2015-06-18) -- "World-Famous Astronaut"

> Thank you for looking at this issue.
