Hello all,
I've run a Spearman's Rank test to discern relationships between landscape
characteristics and a specific aspect of river behaviour.
I've executed a correlation matrix between the one dependent variable and
all of the predictors, which gives me a nice output of Spearman's Rho
values.
However, I also need to somehow find the "p" value, to assess the strength
of relationship.
Conducting a simple correlation between 2 variables using the:
cor(var1, var2, method="spearman")
command gives me an output with both the Rho and P value, but the default
output of the matrix is simply the Rho value. I've tried using
summary(result), but it just produces the percentile/max/min values.
Any help appreciated.
Cheers,
S.
