Unexpected ")" in "

[savita.m20]

Hello all, I am trying to create a boxplot, but R keeps telling me there is an unexpected ")" in my answer, but I am pretty confident all my parentheses match up... here is my script, any help would be very appreciated! I am pretty new to R so I'm just a little confused! Thank you

boxplot (pilot$Percent Germination ~ pilot$Seed Type * pilot$Light Treatment,
xaxt = "n",
xlab = "Treatment",
ylab = "Percent Seed Germination (%)",
col = c("pink", "purple" ),
at = c(1,2, 4,5, 7,8))

Welcome to the community!

I think the problem is being created because you have column names with spaces. Try this once:

boxplot (pilot$`Percent Germination` ~ pilot$`Seed Type` * pilot$`Light Treatment`,
xaxt = "n",
xlab = "Treatment",
ylab = "Percent Seed Germination (%)",
col = c("pink", "purple" ),
at = c(1,2, 4,5, 7,8))

If it does not solve the problem, please provide a minimal reproducible example. For your case, probably dput(head(pilot, 30)) will be enough. Change 30 if it's not appropriate.

Edit

@savita.m20 : Here were the problems:

@savita.m20

pilot$Percent Germination ~ pilot$Seed Type * pilot$Light Treatment

Here you were trying to access Percent Germination, Seed Type and Light Treatment from pilot, and that failed. If you see my snippet, I added backticks (`) before and after these, and it works that way.

Hope that helps. If your problem is solved, will you please consider closing the thread? FAQ link below:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …

That worked! Thank you so much I appreciate it. Also, where was the spacing off, just so I can prevent this mistake in the future! Than you again
