[R] confidence intervals for the difference between group means

[Prof. Dr. Matthias Kohl]

you could try:

library(MKinfer)
meanDiffCI(a, b, boot = TRUE)

Now, I am looking for the confidence intervals for the difference between group means. In my case, the point estimate of the mean difference is 64.4. I am looking at the 95% confidence intervals around this point estimate (64.4).
