Let's say I have these data that show a mean of 49.88 and a SD of 26.056. Now, Let's say I wish to transform the vector x to have a mean 62 and SD of 19. How Can I transform these data to do so?

`alter_mean_sd <- function(x, new_mean, new_sd) scale(x)[, 1] * new_sd + new_mean` ? – Axeman Feb 16 '22 at 17:15
