Sorry to have not provided enough information in my prior post. Here
is a
summary of the calculation set that I am doing. The histograms have
changed
since my last post, but I am not so concerned about them. The
scatter plots
do not show all of the points, they seem to round off to the most
common.
You seem to think that qqplots should be giving you scatterplots. That
is not the case. The qqplot function gives you quantile-quantile plots
and you have given it arguments that implied that temp$R2SC was a
theoretical distribution to which you wanted to compare the
distribution of temp$words
If you want scatterplots, then this would be the way forward:
plot(x=temp$words, y=temp$R2SC, ylab="With Rules applied SC",
xlab="Number of
Words",col="blue",main="Subordinating Conjunctions\n(Number of
Words)")
Or perhaps with some jitter and smaller points to separate identical
values:
plot(x=temp$words,y=jitter(temp$R2SC, factor=2.3), cex=0.1, ylab="With
Rules applied SC",xlab="Number of
Words",col="blue",main="Subordinating Conjunctions\n(Number of Words)")
And given the failure of even that plot to separate the points in that
2.9 MB file, then perhaps look at density plot strategies.

I
have tried doctoring the http://n4.nabble.com/file/n963172/ESTATS
ESTATS
file to get a different result, but received no change.
removeOutliers<-function(dataset){
return(
dataset[
max(sort(dataset$words)[1:(length(dataset$words)/100)])<dataset
$words &
dataset$words<(min(sort(dataset$words)[(99*length(dataset$words)/
100):length(dataset$words)])+1),,
]
)
};
edat.src<-read.csv("ESTATS",head=TRUE,sep="\t");
edat<-removeOutliers(edat.src);
# Only address the subset where there exists appropriate
conjunctions within
the sentence
temp<-edat[edat$R2SC>0,,]
png("egraph_rules_list_2.png",width=800,height=700,res=72);
par(mfrow=c(2,2));
# graph that i am having trouble with, it does not seem to reflect
the data
# The scatter plots are not recognizing all of the data
qqplot(x=temp$words,y=temp$R2SC,ylab="With Rules applied
SC",xlab="Number of
Words",col="blue",main="Subordinating Conjunctions\n(Number of

hist(temp$words,col=heat.colors(max(temp$words)),main="Subortinating
Conjunctions \n-- Number of Words");
temp<-edat[edat$R2CC>0,,]
qqplot(x=temp$words,y=temp$R2CC,ylab="With Rules applied

hist(temp$words,col=heat.colors(max(temp$words)),main="Coordinating

You provide no data. This is a guess, therefore. You have used a hist
call that has a ratio as the argument and were expecting it to be
interpreted as a formula.
