Removed rows containing missing values (geom_point).

[jspegarova]

Hi

I get the warning message below after the line
lgd <- get_legend(p2 +
guides(color = guide_legend(ncol = 2, override.aes = list(size = 3))))

Warning message:
Removed 718647 rows containing missing values (geom_point).

Any idea of where this is coming from and how to solve it?

Thanks for your help.

Hard to diagnose without more details, but maybe it's actually ok as it's only a warning and maybe p2 already makes a figure? Is it simply that you have many cells, but only calculate the tSNE projection for a small number (e.g., 500) of cells and thus the rest are NA (missing). If so, then it's not really a problem.

In general, it's best to give a reproducible example, and the output of sessionInfo().

Yes, if p2 is a dim red plot, it is most likely because the dim red was run only a subset of cells and thus contains NAs for many cells. The warning will be suppress in the next devel version as it shouldn’t be reason for concern.
