Hi friends,
Any idea why do i get this warning?And also why all computed p-values are
NaN.
Have shown below what i did in Windows r-console.:--
> df
c1 c2
1 1 50
2 NA NA
3 4 NA
4 7 6
5 NA 7
6 10 10
> r<-cor(x=df,y=NULL,use="complete.obs",method=c("pearson"))
> r
c1 c2
c1 1.0000000 -0.9148074
c2 -0.9148074 1.0000000
> cor.p.values<- function(r, n)
+ {
+ df <- n - 2
+ ESTIMATE <- c(cor = r)
+ PARAMETER <- c(df = df)
+ STATISTIC <- c(sqrt(df) * r / sqrt(1 - r^2))
+ p <- pt(STATISTIC, df)
+ return(2 * pmin(p, 1 - p))
+ }
> cor.p.values(r,2)
[1] NaN NaN NaN NaN
*Warning message:
In pt(q, df, lower.tail, log.p) : NaNs produced
*
Any help will be appreciated.. :)
