Having problem while Calculating mean body weight of two groups over 5 weeks and plotting in R studio

I have body weights of two groups, over 5 weeks. First I want to calculate the mean and S.D. of the body weight of each week for each group. Then I want to plot them in a line plot, x axis = Weeks and Y axis = mean body weight, in a single graph. Please help. Also attaching the picture from the CSV file. I am also confused if it is a time series data. In all the time series data, I see they have used date. I dont have any dates in my data. Its Week1, Week2, Week3 and so on.

Hello, welcome to the forum.

What have you tried so far?
what is your specific problem?
we are more inclined towards helping you with specific coding problems rather than doing your work for you.

The forum formatted table is not convenient for forum users to load into their R environments, therefore it will be good to learn about more convenient methods to share. That said could you please turn this into a self-contained 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:
