VBA - Loading Arrays, Skipping Blanks

Asked 2021-Jun-15 at 19:54

Sorry I don't show my variables or anything, tried to give information only pertaining to the questions. This 1 Sub is huge.

Currently my code allows a user to select multiple files, the files selected will be sorted in a specific format, then loaded into 2 different arrays. Currently loads Columns D:E into 1 array and Columns I:K into another array (from selected files QSResultFileWS, and returns those arrays to my destination FormattingWS. I'm still trying to learn arrays so if the methodology I used to do this isn't proper, be gentle.

You can use the FILTER function to remove the blanks.

Your code is correct, you need to transpose the result as apply always returns a transposed result (See Why apply() returns a transposed xts matrix? ).

QUESTION

spec_tbl_df is over 10 times slower on same opperations as a normal tibble

Asked 2021-Jun-15 at 14:37

So I was really ripping my hair out why two different sessions of R with the same data were producing wildly different times to complete the same task. After a lot of restarting R, cleaning out all my variables, and really running a clean R, I found the issue: the new data structure provided by vroom and readr is, for some reason, super sluggish on my script. Of course the easiest thing to solve this is to convert your data into a tibble as soon as you load it in. Or is there some other explanation, like poor coding praxis in my functions that can explain the sluggish behavior? Or, is this a bug with recent updates of these packages? If so and if someone is more experienced with reporting bugs to tidyverse, then here is a repex showing the behavior cause I feel that this is out of my ballpark.

This is the issue I had in mind. These problems have been known to happen with vroom, rather than with the spec_tbl_df class, which does not really do much.

vroom does all sorts of things to try and speed reading up; AFAIK mostly by lazy reading. That's how you get all those different components when comparing the two datasets.

With vroom:

Restore from Room Sqlite database from sd card not working

Asked 2021-Jun-14 at 08:16

I looked at others answers like Backup and restore SQLite database to sdcard and Restoring SQLite DB file etc. but i still dont see the restoring of database when i uninstall and reinstall app and restore backup. Here is the code I have currently.

...

ANSWER

Answered 2021-Jun-03 at 20:36

You issue could well be that the database is using WAL (Write-Ahead logging) as opposed to journal mode.

With WAL changes are written to the WAL file (database file name suffixed with -wal and also another file -shm). If the database hasn't been committed and you only backup/restore the database file. You will lose data.

When fully committed, the -wal file will be 0 bytes or not exist, in which case it is not needed.

From Android 9 the default was changed from journal mode to WAL.

https://source.android.com/devices/tech/perf/compatibility-wal

Assuming that this is your issue you have some options:-

Use Journal mode (e.g. use the SQLiteDatabase disableWriteAheadLogging method)
Backup/Restore all 3 files (if they exist)
Fully Commit the database and then backup (closing the database should fully commit) and delete/rename the -wal file and -shm file before restoring.

Option 3 would be the recommended way as you then gain the advantages of WAL.

Here's an example of fully checkpointing (a little over the top but it works):-

I have a dataframe on which I use psych::alpha. In the output there are general confidence boundaries around a general cronbach's alpha value. I want to access those but they don't appear in the results when I save the output as a variable. In the documentation they're called itemboot.ci but that doesn't exist in the alpha object.enter code here

When you print an object, either by using print or by sending it to the R console, some extra processing may happen. Every object (almost always) has its own print and in this case you can see that the print.psych method (called behind the scenes instead of print on any psych package object) is doing the following with your object of (sub)class alpha:

Arduino Uno, PLX-DAQ and 125Khz RFID reader problem

Asked 2021-Jun-13 at 12:23

Project largely working. Have a 125Khz RFID module on an Arduino Uno, with SD card module and and RTC, all working nicely and passing data via PLX-DAQ to Excel and storing data to SD card.

I need a way of working out when the Uno is connected via PLX-DAQ to USB/serial, or when the Uno is just on battery.

So I thought to set a particular cell on Excel with the PLX-DAQ form macro in VBA to 1 (when connected) or 0 (disconnected) then read that in the Arduino code to determine whether to pass data via serial to excel or pull stored data off SD card.

The cell J4 toggles 0 or 1 according to whether disconnected / connected.

I then use the GET function of PLX-DAQ to read a cell from the Arduino sketch.

To upload the sketch I have to disconnect the connection between the RFID Tx and Arduino Rx or I get an error, which is normal, and if I run the sketch with that wire disconnected GET works fine.

ANSWER

Answered 2021-Jun-12 at 01:54

I assume you leave the arduino TX wire connected to the PC-RX. Thats why your PLX-DAQ still has the input. And as you suspect nothing will be going back.

First I thought, since nothing will come back, so your code will be stuck on

1. The first change to make to understand your output is the final print. Change it to an f-string or print the message and the output using separate print's. When you do print('some text\n', output) the comma gets inserted as a space after the newline and skews the top row of your output. How it looks when correct:
