Good morning sir, I have collected 800 soil samples from different districts of Manipur State in India. The soil samples were analysed for different forms of soil acidity. Sir I wish to prepare a soil acidity map of Manipur state using my data. Sir Could you share some of your knowledge to prepare.

Would it be possible to have multiple output directories, such as revealjs for one folder and html for another?
@jfrench
@jfrench 5 месяцев назад
The answer should be yes, but I'm not sure you can do both at the same time. And you may need to do a "manual" version of this where you comment/uncomment parts of your YAML header to get the different behavior, requiring you to compile it two times.

Hi Joshua, Interesting video! I was experimenting with permutation tests in regression and found my p-values for coeffcients are simular to those generated by using a t distribution. The one exception seems to the p-values for the intercept term. Is there a reason for this? Do you know of any way to correct for it? Thanks.

why would you round that up if the next number to that decimel value is below 5?
@lotusbogus
@lotusbogus 10 месяцев назад
You always round up even if decimal is lower than 5 so 4.2 is rounded up to 5 and 6.1 is 7 and so on.

What does "deploy is waiting for github-pages deployment approval" mean? I have completed all the same steps outlined in your videos but reach this point as part of the actions and I wait upwards of 10-15 minutes with no deployment of the page.

Hi Will, you shouldn't need to do anything under Actions, only the Pages settings.
@willdecker4695
@willdecker4695 Год назад
@@jfrench Thanks for the reply. I figured out the issue...I was using regular markdown files (.md) and not quarto files (.qmd) and fixing this seemed to allow my page to deploy!

You always should be gIven that, it’ll either be bin width or some categorical number that tells you how many groups.
