How to subset in ggplot?

I want to remove "No Preference" and "Uncommitted" from my ggplot Heatmap on the y axis, but the subset just doesn't work, do you know the possible reasons ?

My code:

ggplot(subset(primary_results, candidate != c("No Preference", 
"Uncommitted"))) + 
geom_tile(aes(y = candidate, x = state_abbreviation, fill = fraction_votes))  
+ 
scale_fill_viridis(option = "plasma") +
theme_solarized_2() +
xlab("State") +
ylab("Candidate") +
guides(fill = guide_legend(title="Fraction Votes"))

My Heatmamp (notice, I still get the unwanted part)

If I try the subset outside the plot, it also just doesn't work..

The problem is your subset. You have removed all candidates not equal to the length two character vector c("No Preference", "Uncommitted").

I think you want:

ggplot(subset(primary_results, !(candidate %in% c("No Preference", "Uncommitted")))) +
