QUESTION

How to look up data in a separate dataframe (df2) based on date in df1 falling between date range values across two columns in df2

Asked 2021-Jun-15 at 16:38

Situation: I have two dataframes df1 and df2, where df1 has a datetime index based on days, and df2 has two date columns 'wk start' and 'wk end' that are weekly ranges as well as one data column 'statistic' that stores data corresponding to the week range.

What I would like to do: Add to df1 a column for 'statistic' whereby I lookup each date (on a daily basis, i.e. each row) and try to find the corresponding 'statistic' depending on the week that this date falls into.

I believe the answer would require merging df2 into df1 but I'm lost as to how to proceed after that.

Appreciate any help you might provide! Thanks!

df1: (note: I skipped the rows between 2019-06-12 and 2019-06-16 to keep the example short.)

age date 2019-06-10 20 2019-06-11 21 2019-06-17 19 2019-06-18 18

df2:

wk start wk end statistic 2019-06-10 2019-06-14 102 2019-06-17 2019-06-21 100 2019-06-24 2019-06-28 547 2019-07-02 2019-07-25 268

Desired output:

age statistic date :--- :-------- 2019-06-10 20 102 2019-06-11 21 102 2019-06-17 19 100 2019-06-18 18 100

Assuming what I mentioned in my comment on your question, the fix is just to simplify your FieldWithConfidence type significantly. Right now it is trying to add a number of additional levels of structure beyond what you seem to want. Here is a version of that type that works as I think you intend:

QUESTION

How can I align TextSpan children which have different sizes, along the middle in Flutter?

Asked 2021-Jun-15 at 07:31

I have three TextSpan children as per the image attached - with the middle TextSpan object a larger font size.

I want all three TextSpan objects to be centered against the background parent.

When the fonts are all the same size they are aligned along the center horizontally. However when I increase the font size of one TextSpan, only the larger text object remains centered and the smaller two fonts fall to the larger font's base)...

I have tried different alignment properties but cannot work it out. Can this be done with TextSpan text?

Thanks!

You can use WidgetSpans to make sure all your elements(text or not) are vertically centered

R - Place Longitude and Latitude coordinates into a 2x2 grid

Asked 2021-Jun-14 at 12:33

I have a dataframe with Longitudes and Latitudes and I would like to create a 0.5x0.5 degrees grid that shows which lat, long fall within it. So far, I have tried several solutions, including some found here on stackoverflow, that use cut and expand.grid as well as code that uses the package "sp" but none has worked out for me (maybe I simply can't implement them).

Any suggestions on how I can group my data into a 0.5x0.5 degrees grids?

Latitude Longitude 31.602 -39.848 31.675 -39.467 31.747 -39.083 32.152 -36.795 32.218 -36.408 32.285 -36.022 32.348 -35.635 32.412 -35.247 32.475 -34.858 32.535 -34.47 32.595 -34.082 32.677 -33.707 32.763 -33.323
