Hi, there:

As you all know, correlation is not a very robust procedure. Sometimes correlation could be driven by a few outliers. There are a few ways to improve the robustness of correlation (pearson correlation), either by outlier removal procedure, or resampling technique.

I am wondering if there is any R package or R code that have incorporated outlier removal or resampling procedure in calculating correlation coefficient.

Your help is greatly appreciated.
