aq.trans: Annual transition data for Aquilegia chrysantha

Description

Transition data listing stages and fates from Aquilegia chrysantha in Fillmore Canyon, Organ Mountains, New Mexico, 1996-2003.

Usage

aq.trans

Arguments

Format

A data frame with 1637 rows on the following 9 variables:

plot: Plot number
year: Staring year of census
plant: Plant id number
stage: Initial stage class with ordered factor levels seed < recruit < small < large < flower.
leaf: Total number of leaves
rose: Total number of rosettes
fruits: Total number of mature fruits
fate: Final stage class or fate with levels seed < recruit < small < large < flower < dead
rose2: Final number of rosettes

Details

The five stage classes include seeds in the seed bank, new recruits or seedlings, small vegetative plants with 1 rosette, large vegetative plants with 2 or more rosettes, and flowering plants. Stage classes were assigned to census plants using a combination of status and size data recorded in the field. See demo(stage.classify) for more details.

Examples

Run this code

head2(aq.trans)
sv <- table(aq.trans$stage, aq.trans$year)
addmargins(sv)
stage.vector.plot(sv[-1, ], prop = FALSE, main = "Aquilegia stage vectors")
## plot proportions with barplot
## use xpd to draw legend outside plot boundaries
op <- par(mar = c(5, 4, 4, 1), xpd = TRUE)
x <- barplot(prop.table(sv[-1, ], 2),
  las = 1, col = 1:4, ylim = c(0, 1),
  xaxt = "n", space = .5, xlab = "Year", ylab = "Proportion in stage class"
)
yrs <- substr(colnames(sv), 3, 4)
axis(1, x, yrs)
legend(2.7, 1.25, rev(rownames(sv)[-1]), fill = 4:1, bty = "n", ncol = 2)
