areadens2D: Area vs. x-axis

In qtlc: Densitometric Analysis of Thin-Layer Chromatography Plates

Description

Function charts density plot of a single spot following x-axis.

Usage

areadens2D(object, spot = NULL, plot = TRUE, returndf = TRUE,
  ptype = "o", ...)

Arguments

object	S3 object of working TLC
spot	Number of the spot (counted left to right).
plot	Boolean, TRUE default and displays densitometric distribution.
returndf	Boolean, TRUE by default, returns data.frame with x and Area values.
ptype	Point type for the plot. Default "o" (Uses same values as type variable from plot function)
...	Additional parameters (for plot type function).

Value

Returns data.frame with x and Area values.

Examples

# A test example
fname01 <- system.file("extdata", "test025to100sp.tiff", package="qtlc")
testTLC <- createTLC(fname01, RGB=FALSE)
print(testTLC)

# now we'll imitate interactive spot2D function,
# and create spots coordinates automatically,
# for interactive version run testTLC <- spot2D(testTLC)
testTLC$spots$x <- c(40.93354, 83.18687, 121.59899, 160.01111, 203.54485,
                     239.39616, 280.36909, 320.06161, 362.31494, 399.44666,
                     439.13919, 480.11211, 518.52423, 559.49716, 599.18969)
testTLC$spots$y <- c(198.3160, 198.3160, 199.2833, 198.3160, 198.3160,

testTLC <- select2D(testTLC, 30, 30)
testTLC <- matrices2D(testTLC)
testTLC <- summat2D(testTLC)

# and now test the areadens2D for each spot

areadens2D(testTLC, spot=i, ptype="l")
}
