So are the names of the columns in the dataset x, y, and z? or are
they area, concentration, and year? you seem to be mixing these
together? If you provide a minimal reproducible example (provide some
data with dput, or the commands to generate random data, or use a
built in dataset) then it
Hi,
Try:
set.seed(49)
dat1 - data.frame(year=
rep(2010:2013,c(10,8,9,13)),x=sample(1e4,40,replace=TRUE),y=sample(40,40,replace=TRUE))
plot(x~y,data=dat1,subset=year 2012)
#or
with(subset(dat1,year 2012),plot(y,x))
A.K.
Hi R people
This might take me the whole day to figure out, instead

Let's look at your data frame:
str(daily.sub1)
'data.frame': 9 obs. of 4 variables:
$ Trial: Factor w/ 1 level 2: 1 1 1 1 1 1 1 1 1
$ Tanks: Factor w/ 3 levels a4,c4,h4: 1 1 1 2 2 2 3 3 3
$ Day : Factor w/ 9 levels
Here is a runable program. When I plot Day and Wgt, it graphs all the data
points. All I need is daily.sub1 plotted. I also need each Tanks to have
its own col or pch. When I run it with the line with pch, it gives me
nothing.
rm(list=ls())
Trial-rep(c(1,2),each=12)

DF -
The problem is with attach. You should have seen an error that the
objects are aliased. You have Tanks in your workspace and in the
attached dataframe. It is using the one in your workspace which is not a
factor variable. Try:
c(2,19,21)[Tanks]
with(daily.sub1,c(2,19,21)[Tanks])

I tried the following and still could not get it to work. I understand your
logic, but cannot get this to work.

Trial-rep(c(1,2),each=12)
Tanks=rep(c(a3,a4,c4,h4),each=3,2)
Day=rep(c(1:12),2)
Wgt=c(1:24)

daily.sub-subset(daily,
What did you ***expect*** or hope to get out of
``c(2,19,21)[Tanks]''
Please note that this expression makes no sense at all as it stands.
You apparently want to use plotting symbols 2, 19, and 21 respectively,
depending in some way upon the value in ``Tanks''. Since you have

Don't need to convert the factors to numeric as that will happen
automatically. See below. However as Rolf pointed out they will be
numbered from 1-4 even though only 3 are left in the subset as all 4
levels are maintained. So the snippet below will work as long as you
specify 4 possible
create a subset for brook_dis. When I plot (week, R) I get a nice
boxplot, but along the x axis, there are weeks a, b, c along with h and
nh.
Thank you ahead of time. keith
