Dear All,
I Have a dataframe like that:
Name1 Name2 category
mauro francesco E234
luca giuseppe E5578
luca franco E5569
maria luca E4556
...
I would like to calculate the frequency of many time in my data I found in
the list name:
a<-read.table("pippo.csv",header=T,sep="\t")
name1<-as.character(a[,1])
name2<-as.character(a[,2])
category<-as.character(a[,3])
for(i in 1:lenght(name1)){
re <-which(name1 == name2)
}
So how can create a table of frequncy of many times I found a name in column
one respect to the second ?
Thanks in advance for your help!
M.
