Dose-reponse plot for target items
targetplot.RdPlots dose-response raw data of target items (whether or not their response is considered significant) with fitted curves if available.
Arguments
- items
A character vector specifying the identifiers of the items to plot.
- f
An object of class
"drcfit".- add.fit
If
TRUEthe fitted curve is added for items which were selected as responsive items and for which a best fit model was obtained.- dose_log_transfo
If
TRUE, default choice, a log transformation is used on the dose axis.

See plot.drcfit.
Examples
# 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")
#> Just wait, the normalization using cyclicloess may take a few minutes.
s_quad <- itemselect(o, select.method = "quadratic", FDR = 0.01)
#> Removing intercept from test coefficients
f <- drcfit(s_quad, progressbar = TRUE)
#> The fitting may be long if the number of selected items is high.
