R 3.4.2 OS X Colleagues
I would appreciate some help with regular expressions. I have string that looks like: " ITERATION ,THETA1 ,THETA2 ,THETA3 ,THETA4 ,THETA5 ,THETA6 ,THETA7 ,SIGMA(1,1) ,SIGMA(2,1) ,SIGMA(2,2)” In the entries that contain: (X,Y) # for example, SIGMA(1,1) I would like to replace the comma with a period, e.g., SIGMA(1.1) but NOT the other commas The end-result would be: " ITERATION ,THETA1 ,THETA2 ,THETA3 ,THETA4 ,THETA5 ,THETA6 ,THETA7 ,SIGMA(1.1) ,SIGMA(2.1) ,SIGMA(2.2)” Can someone provide the regular expression code to accomplish this? Thanks.
