Unimplemented type list when trying to write.table
Do this, irrespective of how many columns you have: Then do write.csv.
Do this, irrespective of how many columns you have: Then do write.csv.
setnames from the data.tablepackage will work on data.frames or data.tables Note that changes are made by reference, so no copying (even for data.frames!)
You get this warning because the min/max are applied to numeric of length 0 argument. This reproduces the warning. Note that for mean you don’t get the warning : It is just a warning that don’t have any effect in the computation. You can suppress it using suppressWarnings: EDIT Above I am just answering the question: What’s the … Read more
The value of R becomes zero at some point; it leads to a non-finite value of the function to be minimized and returns an error. Using the argument log=TRUE handles better this issue, see function LL3 below. The following gives some warnings but a result is returned, with parameter estimates close to the true parameters.
If you can check the lengths of nb_test_predict and testmyData$cncl_flag by using length() function, you will understand the reason for the error.
Here is a plotrix solution: And here is a ggplot solution: UPDATE: Here is a base solution to your edits:
Because of the thousand separator, the data will have been read as ‘non-numeric’. So you need to convert it: and now you can do and other numeric operations.
I think you’re asking how to compute the mean of a variable in a data frame, given the name of the column. There are two typical approaches to doing this, one indexing with [[ and the other indexing with [:
You need to supply one more column name. Your data has eight columns, as can be seen, e.g., with or or by displaying the matrix: while You could try with With your data, this would be: which gives: without any error message.
It seems you using unicode characters in your code: ”p =”,p). Replace by
