Me gustaría colocar mis etiquetas en el piechart, no en la leyenda. En otras palabras, me gustaría que el nombre de la fiesta aparezca centrado en el gráfico en lugar de a la derecha. ¿Cómo haría esto?

Muestra DF:

> data_party$party[1:20]
 [1] "Independents" "Independents" "Independents" "Independents" "Democrats"   
 [6] "Democrats"    "Democrats"    "Democrats"    "Independents" "Independents"
[11] "Democrats"    "Democrats"    "Democrats"    "Democrats"    "Democrats"   
[16] "Independents" "Democrats"    "Democrats"    "Independents" "Democrats" 

Vector de muestra de la columna:

# pie graph for party
data_party <- subset(data, subset=!is.na(data$Q7))
data_party$party[data_party$Q7==1]<-"Democrats"
data_party$party[data_party$Q7==2]<-"Republicans"
data_party$party[data_party$Q7==3]<-"Independents"
data_party$party[data_party$Q7==4]<-"None"
pie <- ggplot(data_party, aes(x = "Party Affiliation", fill = factor(party))) + geom_text(aes(y = party, label=party)) + geom_bar(width = 1) + theme(panel.background = element_blank())
pie + coord_polar(theta = "y") + theme(legend.title=element_blank())+ theme(axis.title.x = element_blank()) + theme(axis.title.y = element_blank())
