Hi all,
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. Kind Regards, Praveen.
