[R-br] correlação de pearson

[Guilherme Parreira da Silva]

2: package ‘ppcor’ is not available (for R version 2.15.1) = Esse pacote não funciona nessa versão do R.

Use a função cor()... cor(Y~X, method = "pearson")

package ‘ds’ is not available (for R version 2.15.1) = Mesmo caso que o de cima.
