Hello,
I am trying to produce some graphics to visualize my data. I think I want
histograms. I have a grouping variable that has 48 different groups. I would
like to produce a graphic that contains three of of these groups in the same
device (they are time steps). I would like create graphics for about 6
different variables (6 variables X 16 groupings of there = 96 graphics). I
am unsure of how to tell R which of three groups to use from the grouping
variable (its values are numeric) and then how to put all three to the same
device.
I tried:
> names(all)
[1] "tally" "scape" "numid" "bbContag"
"bbED"
[6] "bbENN_MN" "bbLPI" "bbLSI" "bbPAFRAC"
"bbPD"
[11] "bbPROX_MN" "pfor" "year" "extent"
"bi_ca"
[16] "r" "ex_bin" "PriNo" "pri1234"
"pri_ex"
[21] "sc_ex" "Sc_ex_pri" "sc_recov" "recov_bica"
"sc_reco_bica"
[26] "sc_ec_p1234" "Pri_No" "id_no" "RecovUnit"
"Max_est"
[31] "F23" "F24" "F25" "F26"
"F27"
[36] "F28" "F29"
> histogram(~ sc_recov | bbPD, type="count")
This opened a device, but nothing was there, probably because I made R angry
because I think it was using all the rows ~5,000. I then tried using a
barplot, which worked but it was also a lot dense and not what I was looking
for visually. I'd appreciate any comments about these multiple questions,
including helpful 'read the manual' suggestions.
Thank you kindly,
M Just
