The error message says you have duplicate row names and that
is not allowed. Make sure you have the same number of elements
on each line of data as in the header. If you have one more on each line
than on the header then the first data item on each line will be regarded
as the row name. See ?cou
hi gabor,
i was able to get your suggestion to work. i have been going through
the R help tools to figure out what each step actually does because i
have something similar but hours 2,5,8,11,14,17 and 20 are missing. i
haven't had any luck. each "mean value" that is calculated is the
same.
Following Gabor's suggestion, if x is your data.frame
you can do
y <- x[x$month %in% c(3,4,5),]
aggregate(y[,4:6],list(y$hour),mean)

Just adjust the formula for Qtr appropriately if your quarters
are not Jan/Feb/Mar, Apr/May/Jun, Jul/Aug/Sep, Oct/Nov/Dec
as I assumed.

Hi Gabor,
Thank you for your help. I think I need to clarify a bit more. I am
trying to say
average all 2pms for months march + april + may (for example). I hope this is
clearer.
here's a larger subset of my data set:
year, month, hour, co2(ppm), num1,num2
2006 1 0 384.2055 14 14
2006 1
Try aggregate:
Lines <- "Year Month Hour co2 num1 num2
2006 110 383.3709 28 28
2006 111 383.3709 28 28
2006 112 383.3709 28 28
2006 113 383.3709 28 28
2006 114 383.3709 28 28
2006 115 383.3709 28 28
2006 116 383.3709 28
