Solving the error: error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, …) : 0 (non-na) cases
The cause: Because variables x or y or both x and y have only NAs, the lm(y x) command appears as an error. Solution: Before your lm commands, for example: I recommend testing if one of the variables contains all NAs: all(is.na(x)) all(is.na(y)) all(is.na(y^trans)) For instance: all(is.na(y)) [1] TRead more

Error in .call.graphics(c_palette2, .call(c_palette2, null)): invalid graphics state – simple way to solve it
The cause: The error invalid graphics state occurs as the present plot window is too small to satisfy the requirements of the displayed plot. Solution: You should expand the plot window by deleting all the plots in the console to create a large plot area. Then, the graphics state will not be reporteRead more
The cause: The error invalid graphics state occurs as the present plot window is too small to satisfy the requirements of the displayed plot.
Solution: You should expand the plot window by deleting all the plots in the console to create a large plot area. Then, the graphics state will not be reported error anymore.

The cause: The problem that the file or directory is not found can be caused by running pip install "ipython[notebook]". Because it muddles everything. Solution: To solve the problem, you should reinstall from PyPi and run like this: # For Python 2 pip install --upgrade --force-reinstall --no-cache-Read more

The dim(x) must have a positive length error: what should you do?
The cause: The error appears because R coerces last_visit[,2] to a dimensionless vector, whereas apply needs to have some dimensions of the object. Solution: You can stop the compulsion by adding drop=F to the command: apply(last_visit[,2,drop=F], 1, best_recom) Or on the vector, you use lapply or sRead more

The cause: This is called the "order line". It usually involves a "Purchase Order" consisting of many lines or one line. Solution: It is usually stored as the following example: (This is a [ORDERS] table with one row and a [Order-Lines] table with three rows which point towards the parent row.) [ORead more
