targetplot: Dose-reponse plot for target items

Description

Plots dose-response raw data of target items (whether or not their response is considered significant) with fitted curves if available.

Usage

targetplot(items, f, add.fit = TRUE, dose_log_transfo = FALSE)

Arguments

items

A character vector specifying the identifiers of the items to plot.

f

An object of class "drcfit".

add.fit

If TRUE the fitted curve is added for items which were selected as responsive items and for which a best fit model was obtained.

dose_log_transfo

to put at TRUE to use a log transformation for the dose axis.

Value

a ggplot object.

Examples

# NOT RUN {
# A toy example on a very small subsample of a microarray data set) 
#
datafilename <- system.file("extdata", "transcripto_very_small_sample.txt", 
package="DRomics")

o <- microarraydata(datafilename, check = TRUE, norm.method = "cyclicloess")
s_quad <- itemselect(o, select.method = "quadratic", FDR = 0.01)
f <- drcfit(s_quad, progressbar = TRUE)

# Plot of chosen items with fitted curves when available 
#
targetitems <- c("88.1", "1", "3", "15")
targetplot(targetitems, f = f)

# }
# NOT RUN {
# The same plot in x log scale
#
targetplot(targetitems, f = f, dose_log_transfo = TRUE)

# The same plot in x log scale choosing x limits for plot
if (require(ggplot2))
targetplot(targetitems, f = f, dose_log_transfo = TRUE) + 
        scale_x_log10(limits = c(0.1, 10))

# The same plot without fitted curves 
#
targetplot(targetitems, f = f, add.fit = FALSE)
