Error in match.arg(alternative) FOR CORRELATION TEST

[student2]

Hi! I am trying to use use the correlation function in R studio by using the pearsons method but this coding error keeps on appearing: Error in match.arg(alternative) : **
** 'arg' must be NULL or a character vector

this is the coding:

cor.test(analysis$art, analysis$SNP500, method=c("pearson"), conf.level=0,95, use="complete.obs")

thank you in advance!
