hi,
i am using R for first time. i am trying to do T-test for a sample set with
three variables. i attached my data set as CSV file.
but when i do "t.test(data$Day.1,data$Day.2,var.equal=T)" i get this
following error. Can anyone please help e identify the problem.
Error in if (stderr < 10 * .Machine$double.eps * abs(mx)) stop("data are
essentially constant") :
missing value where TRUE/FALSE needed
In addition: Warning message:
In mean.default(x) : argument is not numeric or logical: returning NA
Thanking you in advance.
