您可以使用add=T

data<-c(78,100,90,100,96,100,100,82,95,99,100,97,79,99,100,77,79,100,95,100,100,100,82,77,82)
hist(data, xlab="Score",breaks=c(75,80,85,90,95,100),ylab = "Frequency", main = paste("Score Distribution"), cex.main = 1.55, cex.lab = 1, freq = TRUE)

newdata <- data[data == 100]

hist(newdata, xlab="Score",breaks=c(75,80,85,90,95,100),ylab = "Frequency", main = paste("Score Distribution"), cex.main = 1.55, cex.lab = 1, freq = TRUE, col="red", add=T)
