Hi.
I'm a student in biology and just begin working with RStudio.
I'm building a ggline plot with the jitter option. I see that the error bars that are used by default to creat the plot are the standard errors ("mean_se") of the data set. I'd like to replace them with confidence intervals (level 95%) but i don't know how to do that. I tried replacing "mean_se" with "mean_ci" but it doesn't seem to work and i don't know if i need to put an argument in mean_ci 's brackets.
I'd really appreciate some help.
Thank you
Can you provide a reproducible example?
Otherwise, have a look at these articles. You should be able to do what you need.
Ok.
That is part of my data set

and I only use this line of code in order to create the plot :
ggline(scatter.plot.masse, x = "temps(semaine)", y = "masse", add = c("mean_se", "jitter"))
It is the "mean-se" in bold that i'd like to replace with a confidence interval (level 95%) to appear in my plot.
Can't you just use add = c("mean_ci", "jitter")?
From Line plot — ggline • ggpubr
add
character vector for adding another plot element (e.g.: dot plot or error bars). Allowed values are one or the combination of: "none", "dotplot", "jitter", "boxplot", "point", "mean", "mean_se", "mean_sd", "mean_ci", "mean_range", "median", "median_iqr", "median_hilow", "median_q1q3", "median_mad", "median_range"; see ?desc_statby for more details.
Then when you run ?desc_statby is says it is a 95% CI on the mean.
I don't know why i didn't even think about it. It worked !
Thank you so much for replying that fast and being available.
