Hi,
I'm really struggling with barplot
I have a data.frame with 3 columns. The first column represents an
"incident" type
The second column represents a "month"
The third column represents a "time"
Code for a sample data.frame
incidents <- rep(c('a','b','d','e'), each =25)
months <- rep(c(1,2), each =10)
times <-rnorm(100)
# make my sample data
DF <-
data.frame(Incidents=as.factor(incidents),Months=as.factor(months),Time=times)
# now calculate a mean for the "by" groups of incident type and month
pivot <-
aggregate(DF$Time,by=list(Incidents=DF$Incidents,Months=DF$Month),FUN=mean,simplify=TRUE)
What I want to create is a bar plot where I have groupings by incident type
( a,b,d,e) and within each group
I have the months in order.
So group 1 would be Type "a"; month 1,2;
group 2 would be Type "b"; month 1,2;
group 3 would be Type "d"; month 1,2;
group 4 would be Type "3"; month 1,2;
I know barplot is probably the right function but I'm a bit lost on how to
specify groupings etc
TIA
