Hello. I'm a newbie here.
In my script (I name it readData.R), I wrote the followings:
readData <-function(){ med = read.csv("medicalData.csv");}
Then I tested the script by 'Source R Code' then on the command I typed
'readData()' then I typed 'med' to check if the variable contains the medical

Hello.
I'm trying to compute median for a filtered column based on other column but
there was something wrong. I'll show how I did step by step.
Here's the data:
a b c class
1 12 0 90 A-B2 3 9711 A-B3 78 NA123 A-C4
NA NA12A-C5

Hello.
Thanks for the help and your reasonable explanation. I'll definitely start
using 'dput' next time.
Apologies for the trouble to all who helped me.

Hello.
I'm trying to scaling these attribute values using sigmoid and I created a
function as followed:
mySigmoid <-function(){ medGen = read.csv("medB1.csv"); data(medGen);
medGen.signorm=rangenorm(medGen,method="signorm"); op=par(mfrow=c(2,3))
plot(medGen.signorm[,1])par(op)
Please nevermind as I have just solved this.

Hello.
I'm trying to plot clusters for all possible combination of attributes.
So I typed in
plot(pr2NewMedicalData, col = kmpr2NewMedicalData$cluster)
The problem is it only plots PC2 axis against PC1 axis. There should be PC1 to
PC10. I tried it on normal data (not PCA) and it plots all possib
Please nevermind as I've just solved this by using scatterplot matrices.

Hello.
I'm trying to see clusters into a certain number of classes as seeing they are
too many of them see entirely on dendrogram. So I did the following:
> d <- dist(as.matrix(medData))> hc <- hclust(d, method="average")> plot(hc)>
> plot(hc, hang = -1)
But when it came to this:> rect.hclust(hc
15 matches
