I have done a scatter plot in R. I want to insert the coefficient of determination R^2 = 0.62 as a text in the plot. I have tried to write R^2 but could not produce R2. I would appreciate it if someone could help me with the syntax. I have tried: expression(paste("", R^2,"=", 0.62)), but it did not produce R squared, rather it gave me error messages. Thanks.

Hi, maybe this works: expression(R^2 * "= 0.62") HTH, Kimmo 4. helmik. 2024, 16.11, Jibrin Alhassan <jibrin.alhassan at unn.edu.ng<mailto:jibrin.alhassan at unn.edu.ng>> kirjoitti: I have done a scatter plot in R.
