[R] Plotting graphs using FOR loop

[ychu066]

I have the following codes but can anyone make it shorter i.e making these
FOR loop into one loop ...
thanks...

par(mfrow=c(2,4))                 
for(i in 16:23){
hist(data[,i],main=paste(colnames(data)[i],sep=""),ylab="Frequency",xlim=c(1,5),xlab="Score",ylim=c(0,100)) 
}   
png("histogram.png")
dev.off() 

par(mfrow=c(2,4))                 
for(i in 24:31){
hist(data[,i],main=paste(colnames(data)[i],sep=""),ylab="Frequency",xlim=c(1,5),xlab="Score",ylim=c(0,100)) 
} 
png("histogram.png")
dev.off() 

par(mfrow=c(2,4))                 
for(i in 32:39){
hist(data[,i],main=paste(colnames(data)[i],sep=""),ylab="Frequency",xlim=c(1,5),xlab="Score",ylim=c(0,100)) 
} 
png("histogram.png")
dev.off() 

par(mfrow=c(2,4))                 
for(i in 40:47){
hist(data[,i],main=paste(colnames(data)[i],sep=""),ylab="Frequency",xlim=c(1,5),xlab="Score",ylim=c(0,100)) 
} 
png("histogram.png")
dev.off()
