kandi X-RAY | odin Summary

odin is a R library. odin has no bugs, it has no vulnerabilities and it has low support. However odin has a Non-SPDX License. You can download it from GitHub.

odin implements a high-level language for describing and implementing ordinary differential equations in R. It provides a "domain specific language" (DSL) which looks like R but is compiled directly to C. The actual solution of the differential equations is done with the deSolve package, giving access to the excellent Livermore solvers (lsoda, lsode, etc), or with dde for use with delay differential equations. In addition, the same machinery can be used to generate discrete-time models that proceed over a set of steps (rather than through continuous time). These may be stochastic and make use of any of R's random number functions. odin works using code generation; the nice thing about this approach is that it never gets bored. So if the generated code has lots of tedious repetitive bits, they're at least likely to be correct (compared with implementing yourself).

ANSWER

Answered 2021-May-24 at 14:34

The error message you are getting pretty much tells you what the problem is. You have requested that the package installer notify you on completion by sending a broacast Intent with ACTION = android.intent.action.PACKAGE_ADDED. This broadcast Intent can only be sent by the Android framework. Regular apps cannot send this broadcast Intent.

You should use an explicit Intent, where you specify the component (package name and class name) for this purpose. You can have the package installer launch an Activity or a BroadcastReceiver for this purpose.

NOTE: Your app must be device owner to be able to do this without user interaction.

In the final else, print out playerSelection and computerSelection in quotes. It's most likely a case issue, but you can easily find out what you're comparing.

ANSWER

Answered 2021-Apr-24 at 00:44

Quoting the reference for your problem:

Assignment Objects of array type cannot be modified as a whole: even though they are lvalues (e.g. an address of array can be taken), they cannot appear on the left hand side of an assignment operator:

So, since c in your code is an array object i.e. a type of an array, it cannot appear on the left-hand side of an assignment operator.

QUESTION

Why does my Javascript calculator multiply the answer by 2 when pressing an operator following an equals press?

Asked 2021-Apr-01 at 14:50

I am working my way through The Odin Project and I'm currently stuck on the "Calculator" project.

For the most part, considering my current Javascript knowledge, I am happy with how it works. However; after outputting the result of a calculation by pressing the equals button, if I then press any of the mathematical operators if will then immediately multiply the displayed value by 2 and I can not figure out why.

The calculator can be found here: https://nortski78.github.io/calculator/

To reproduce the bug, enter 5 + 5 = + (that will display 20)

The parts of my code where I believe the problem lies is:

...

ANSWER

Answered 2021-Apr-01 at 12:11

Clicking + calls setOperand. In there if(firstOperand === null) won’t be true, you already assigned a value to that variable before (when you processed the previous + button click), and it never gets “nulled” again anywhere.

So this proceeds with assigning secondOperand, and then it calls operate wrapped in updateDisplay.

So after pressing =, you have to reset your first operand, so that when it goes through setOperand again, it will assign a new first operand first, and only perform the calculation & display update on the second operand.

Install odin

Install odin from CRAN with. Alternatively, you can install a potentially more recent version of odin from the mrc-ide drat repository. You will need a compiler to install dependencies for the package, and to build any models with odin. Windows users should install Rtools. See the relevant section in R-admin for advice. Be sure to select the "edit PATH" checkbox during installation or the tools will not be found. The function odin::can_compile() will check if it is able to compile things, but by the time you install the package that will probably have been satisfied.
