in r corr Cannot compute exact p-value with ties

Use the cor.test() function in R to compute the correlation and p-value for two variables with ties. The function will provide the computed correlation and an approximate p-value, but it will also display a warning message indicating that the exact p-value cannot be computed due to ties in the data. Ties occur when there are identical values in the data, which can affect the calculation of the exact p-value. The warning message serves as a notification that the p-value is approximate due to the presence of ties in the data.
