questions about how to make ggplot with multiple varaince

[rrrrr]

so I have data like this, and I want to make some plots based on it, with y axis represents the mean weight of mice of different days, x-axis represents the time (days), since there are two variables, one is strains , another one is the condition of stress (there are four categories of the combinations of stress train, stress rec1, and stress rec2), I will need to put 8 lines in one plot, I wonder how can I make the ggplot for this? ex. two color used for distinguishing two strains and four types of lines used to represent four combinations of stress condition? I found categorizing those four types combination of stress conditions especially tricky? could anyone help me to write the code for making ggplot of this! thx a lot~

Hi, welcome!

We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
