Hi,
I'm relatively new to R and stuck here. I'm trying to make a line chart using something like the following:
patient_id wk_1 wk_2 wk_3 wk_4 trt_group
<dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
1 1 67 78 34 34 0
2 2 34 54 87 56 1
3 3 45 56 67 88 1
4 4 76 77 79 80 0
5 5 67 66 45 44 0
Where wk_1, 2, 3, 4 represent test scores taken at 4 timepoints, and trt_group represents whether or not the patient recieved the drug.
I need my line graph to look like this:
x axis = the timepoints, so week 1 followed by week 2, etc.
y axis = the average score for that time point
grouped by trt_group, so 2 different lines
I know it should be relatively simple using mutate() and then setting up the plot with ggplot(), but I'm having a serious brain fart.
If anybody could point me in the right direction, it would be much appreciated!
