you start your loop by defining a running variable 'i'. But all over the loop, you redefine it to be other integers and unrelated objects. Such as in line 83, line 155, and others. It's difficult to understand your intentions from the question. but if I understand correctly, the problem can be solved by changing every 'i' in the loop to a differently named temporary variable. A simpler solution would be to change the 'i' variable at the beginning of the for loop to smth else. I suggest you adopt a habit of using variable names that have meaning and not just single or double letters.

I would suggest this would be best implemented with a correlation rather than multiple hard-coded conditions, especially if you have hundreds!

You could have a table - either permanent or a table-valued-parameter passed to your procedure, and implement your filtering using exists

You can get rid of Shared in the DatAccess class. Then each instance of the class will have its own data. Now you must declare an instance of the class and call the method on that instance.

predict function in R sommer v 4.1.1

Asked 2020-Nov-11 at 04:29

In the newest version of the sommer package, some adaptations to the predict function have been made, unfortunately, I am having issues with it in the newest version.

if I do not specify any classify variable:

predict.mmer(modelh) Error in strsplit(classify, ":") : non-character argument

predict.mmer(modelh, classify = "GEN") Error in [.data.frame(object$dataOriginal, , c(colnames(DTX), ignored, : undefined columns selected

my model looks like this:

mmer(data = data, fixed = value ~ 1 , random = ~ GEN + ROWf + COLf + spl2D(ROW,COL), rcov = ~vs(units))

further question: in the model above, I am getting all the same values in the model$fitted vector, which is equal to the intercept. As I understand, the fitted value should also include random effects like GEN, ROWf, ... . Am I misunderstanding something here?

Appreciate any advice, Best Regards, Hermann

ANSWER

Answered 2020-Nov-11 at 04:29

since the 4.1.1 version the predict function is not used anymore to get fitted values, but to obtain adjusted means for an specific classify argument. Therefore, the classify argument cannot be skipped.

If you need fitted values now the fitted() function should return what you're looking for.

Now, the issue with using the classify must come from the use of the spl2D() function outside of the vs() function. You may want to download the newest version from GitHub (version 4.1.2) and try with:

R data.table apply date by variable last

Asked 2020-Apr-11 at 01:55

I have a data.table in R. I have to decrement date from last variable within by group. So in the example below, the date "2012-01-21" should be the 10th row when id = "A" and then decrement until the 1st row. and then for id="B" the date should be "2012-01-21" for 5th row and then decrement by 1 until it reaches first row. Basically the the decrement should start from last value by "id". How could I accomplish in R data.table?

The code below does the opposite. The date starts from 1st row and decrements, how would you start the date by last row and then decrement.
