YSK the date format YYYY-MM-DD is the international standard. It's a great format to use anywhere you put dates. It's especially useful when including dates in file names. This will allow all files to sort by date when sorting alphabetically.
I work as a data analyst for a company with both US and UK offices so always use this format to avoid the confusion of which date format I am using. I’m UK based so all my Computers default to ddmmyyyy and it can cause no end of problems extracting US data. I also have used the Yyyy-mm-dd format for naming files since I can first remember because it was easier to sort in windows file explorer. More on reddit.com

CMV: YYYY-MM-DD is the superior date format
There is something to be said for presenting the most useful information first. We typically don't need to say the year. For example, If i told you I was going to do something January 10th, you would know what I mean. We also don't ways need to say the month. If i told you i'd do something on the 21st, you'd assume i'm meant the 21st of this month. So we we start with the most relevant information first, there a decent debate to be had over whether we should say the day or the month first. But definitely the year is not very relevant. Very often we only need MM/DD or DD/MM. YYYY/xx/xx is a waste of some space. Especially when speaking. In terms of sorting, most of the time dates are stores as dates and rendered in any format selected. So you can sort properly regardless of format. YYYY-MM-DD has its place. Its good when communicating between different applications which don't share a common data structure. Like between Excel and a database. Its also good when embedded into text fields which you want to sort. Although really you shouldn't be doing that. More on reddit.com

Date Format in the United States | ISO
The United States is one of the few countries that use “mm-dd-yyyy” as their date format–which is very very unique! The day is written first and the year last in most countries (dd-mm-yyyy) and some nations, such as Iran, Korea, and China, write the year first and the day last (yyyy-mm-dd).

Why YSK: YYYY-MM-DD is the International (ISO) Standard format for dates. This format makes the most sense for reasons of sorting and also eliminates any confusion due to different date formatting in different regions. This is especially useful when you have files in a folder that have dates in the name.

I like how it simply goes from the biggest measurement (year) to smaller measurement (day) In order. In my home country we do the opposite, going from day to month to year. I NEVER understood why the hell Americans switched the order of day and month just to make things more complicated. Whenever I see 11/10/2020 I am never sure how to read it because of this mixup Americans did.

The built-in date format can't be changed, so don't worry about messing it up. The changes you make will only apply to the custom format you're creating. In the Type box, make the changes you want using code from the table below. If you're modifying a format that includes time values, and you use "m" immediately after the "h" or "hh" code or immediately before the "ss" code, Excel displays minutes instead of the month.

Since dates correspond to a numeric value and a starting date, you indeed need the day. If you really need your data to be in Date format, you can just fix the day to the first of each month manually by pasting it to the date:
month <- "2009-03"
as.Date(paste(month, "-01", sep=""))

Try this. (Here we use text=Lines to keep the example self contained but in reality we would replace it with the file name.)
Lines <- "2009-01 12
2009-02 310
2009-03 2379
2009-04 234
2009-05 14
2009-08 1
2009-09 34
2009-10 2386"
library(zoo)
z <- read.zoo(text = Lines, FUN = as.yearmon)
plot(z)
The X axis is not so pretty with this data but if you have more data in reality it might be ok or you can use the code for a fancy X axis shown in the examples section of ?plot.zoo .
The zoo series, z, that is created above has a "yearmon" time index and looks like this:
> z
Jan 2009 Feb 2009 Mar 2009 Apr 2009 May 2009 Aug 2009 Sep 2009 Oct 2009
12 310 2379 234 14 1 34 2386
"yearmon" can be used alone as well:
> as.yearmon("2000-03")
[1] "Mar 2000"
Note:
"yearmon"class objects sort in calendar order.This will plot the monthly points at equally spaced intervals which is likely what is wanted; however, if it were desired to plot the points at unequally spaced intervals spaced in proportion to the number of days in each month then convert the index of
zto"Date"class:time(z) <- as.Date(time(z)).
