Function cor method="spearman" doesn't work properly

Good day!
I'm trying to find a value of Spearman correlation between two vectors.
The data is here: Ранговая корреляция
The Spearman Correlation Coefficient here is 0.638.

But when I'm trying it in R - the Spearman Correlation Coefficient is 0.484


Please, help me - how to count this coefficient properly?


Hi Olga ,
Welcome to the forum. I am not sure but I think the example in Ранговая корреляция has a mistake in the ranking.

ry for 1958 in Ранги вариант is ranked 6 and I think it should be 9. Therefore, you have the correct result.

rx=c(1.5, 1.6, 2.1, 2.1, 2.2, 2.2, 2.3, 2.3, 2.6, 3.0)
ry=c(1.0, 3.7, 2.4, 2.1, 3.3, 3.6, 3.6, 2.9, 3.0, 4.0)
