Hello,
I am suddenly getting an annoying error every time I try to make a simple variable assignment like B = matrix(c(1,1,0,0,-1,1),nrow = 3)
The Error Message is: <simpleError in is(obj, "ore.frame"): could not find function "is" >
Can anyone help me understand why this is happening and not to get this anymore?
I saw this question was asked here one time but it wasn't really answered. I thank any attempt of help.
