[R] Plotting multiple trends on one graph

[Duncan Mackay]

Hi Natalie

Here is an option using lattice. I think below will get you some way to what
you want

This is your data formatted. in future please dput your data  as your data
was scrambled.
# dput(dat)
dat <- structure(list(TagID = c(4926L, 4926L, 4926L, 4926L, 4926L, 4926L,
4926L, 4926L, 4926L, 4926L, 4926L, 4929L, 4929L, 4929L, 4929L, 
4929L, 4929L, 4929L, 4929L, 4929L, 4929L, 4929L, 4929L, 4929L, 
4929L), Station = c("KLB", "MS01", "MS02", "MS03", "MS04", "MS05", 
"MS06", "MS07", "MS08", "MS09", "MS10", "KLB", "MS01", "MS02",

0.851, 0.629, 0.86, 1.131, 0.9, 0.798, 0.853, 0.694, 0.6, 0.647,

"datetime", "gspd_mps"), class = "data.frame", row.names = c(NA, 
-25L))

# factor of id
dat[,1] <- factor(dat[,1])
# convert to datetime
x <- paste(dat[,3])
x <- strptime(x, "%m/%d/%Y %H:%M")

I have added a few extra formatting options but I will leave you to format
the x labels as an exercise.

# lattice plot conditioned by station
library(lattice)
xyplot(gspd_mps ~ as.POSIXct(x)|Station, dat,
       as.table = TRUE,
       layout = c(1,14),
       groups = TagID,
       strip = FALSE,
       type = c("p","g"),
       par.settings = list(strip.background = list(col = "transparent"),
                           superpose.symbol = list(cex = c(1,0.7),
                                                   col = c("red","blue"),
                                                   pch = c(20,3))),
       strip.left = strip.custom(par.strip.text = list(cex = 0.65) ),
       scales = list(x = list(alternating = FALSE,
                              rot = 90)),
       auto.key = TRUE
       )

# using latticeExtra conditioned by station and tag
library(latticeExtra)
useOuterStrips(strip      = strip.custom(factor.levels = paste("TagID",
unique(dat$TagID)),
                                         par.strip.text = list(cex = 0.85)),
               strip.left = strip.custom(horizontal = TRUE,
                                         par.strip.text = list(cex = 0.75)),
                                         strip.left.lines = 2,
xyplot(gspd_mps ~ as.POSIXct(x)|TagID*Station, dat,

useOuterStrips(strip      = strip.custom(factor.levels = paste("TagID",

       panel = function(x,y, ...){
                 panel.grid(h = 0, v= -1)
                 panel.xyplot(x,y,...)
               }

Thanks for the help!!  I'm very new to R.
