The tutorial @Henrik mentioned is an excellent resource for learning how to create plots with the ggplot2 package. An example with your data: this results in: As mentioned by @user2739472 in the comments: If you only want to change the legend text labels and not the colours from ggplot’s default palette, you can use scale_color_hue(labels = c(“T999”, “T888”)) instead … Read more
Both the code variants that you posted won’t work because they are using the function summarySE() wrongly: Version 1: You use Family as the measurement variable, which means that you ask the function to give you mean, standard deviation, etc. of Family. Version2: You correctly group by Family, but now you supply many measurement variables. This does not work because summarySE() expects a … Read more
It’s hard to tell without a completely reproducible example, but I suspect your problem is this line: id here is a vector, so path becomes a vector of character strings, and when you call read.csv you’re passing it all the paths at once instead of just one. Try changing the above line to and see if that works.
The error (in the title of the post) arises because you have too many arguments to ggplot. As the comments to the question note, the pipeline %>% implicitly includes the output from the left-hand side of the pipe as the first argument to the function on the righthand side. This code replicates the same kind of error. (I’ve … Read more
Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error. – is the ‘binary operator’ your error is referencing, and either CurrentDay or MA (or both) are non-numeric. A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is … Read more
You can just use table(): Then you can subset it: Or convert it into a data.frame if you’re more comfortable working with that:
Based on the comments already given, you can use this code: However, looking at your requested result, it seems that you have the alpha-value as first hex-number in your x – so you need to create a substring:
