jmv::linReg produces wrong intercept coefficients

[jRafi]

When conducting a regression in R and jamovi I get the same intercept coefficients. However, when copying the jamovi syntax to R, I get different coefficients. See values in bold:

R:
> lm("Sepal.Length ~ Species", iris)
Estimate Std. Error t value Pr(>|t|)
(Intercept) 5.0060 0.0728 68.762 < 2e-16 ***

Speciesvirginica 1.5820 0.1030 15.366 < 2e-16 ***

jamovi:
