Hi, the command line with 'text' should be: text(-8,-8, expression(R^2 * " = 0.62, r = 0.79, N = 161"), cex = 2 ) Best, Kimmo su, 2024-02-04 kello 17:16 +0100, Jibrin Alhassan kirjoitti: > Here is the script I used to plot the graph indicating the text I > wanted to > insert.

...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.

Thank you Zhao for the code. When I replotted the graph after inserting the code in my script, it gave me this error message without plotting the graph: Warning message: In lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : extra argument ?col? will be disregarded.
