Bill pointed out some errors in your code but you keep making the claim that
-MM-DD is not recognized and I just want to make it completely clear that
that is the default format for dates in R as it is an ISO standard. So focus on
other issues until you get it working... this format is defin
Please disregard my previous post. My understanding is correct, and the
behavior is **AS DOCUMENTED**.
I failed to read the docs carefully. Mea Culpa.

Notice the as.Date command in the code I sent to you. this converts a
string to a date with a resolution of one day. If you want a higher
time resolu
You left out some calls to c(). Note that
(2,3,5)
is not valid syntax for making a vector of numbers; use
c(2,3,5)
You also left out a comma and gave different lengths for day and value.
You also left out plus signs between the various components of your ggplot
expression.
Try
data <- data
Hi Jim,
Thank you VERY much!
In what I tried, my values for the vertical Y were automatically understood by
R.
But it appears that the string -mm-dd was NOT recognized by R as a date for
the X axis, and gave a red error message.
My values for Year-Month-Day were NOT understood by R.
Is there
David,
Great suggestion!
Thanks,
Brian

1. Please read and follow the posting guide linked below.
2. No html -- this is a plain text list.
3. Use ?dput to provide us your data so that we don't have to convert it
for you.
4. We expect you to first make an effort to do your own coding. See
?t.test, which you could also
have found yourself
By converting the character date data into a time-like type... e.g. ?as.Date
and plotting y-vs-x.

Hi Gregory,
Here's a start:
gcdf<-read.table(text="2020-01-05 15.973

2020-03-10 17.392

Dear R users,
I would like to ask for help with the code of multiple t-test. I have a
dataset as followed:
Species Treatment var1 var2 var2 var4 var5 var6
Blue D 0.022620093 0.125079631 0.04522571 0.010105835 0.013418019

Blue D 0.02117295 0.073544277 0.0311234 0.008742305 0.03261776 0.9
Starting with year-month-day, for the variable gallons, I can easily plot the
variable gallons, while disregarding the date.
gallons <- c (15.973, 18.832, 17.392, 14.774, 19.248, 14.913, 15.226, 14.338,
18.777, 19.652)
plot (gallons, type="l", xlab="X label", ylab="Y label", col="blue”)
How do
