‘text’ draws the strings given in the vector ‘labs’ at the coordinates given by ‘M’ and ‘A’
1 2 | plot.confband.text(x, M, crit1=0.025, crit2=crit1, nclass=10,
labs=NULL, output=FALSE, ...)
|
x |
a vector giving the x-coordinates of the points in the scatter plot. In the microarray context, this could be a vector of average log intensities. ie A |
M |
a vector giving the y-coordinates of the points in the scatter plot. In the microarray context, this could be a vector of log intensity ratios. |
crit1 |
The number of points to be highlighted on the M vs A plot. If crit1 < 1, the crit1*100% spots with the smallest M values will be highlighted. If crit1 >= 1, the crit spots with the smallest M values are highlighted. |
crit2 |
Similar to "crit1". If crit2 < 1, the crit2*100% spots with the largest M values will be highlighted. If crit2 >= 1, the crit2 spots with the largest M values are highlighted. |
nclass |
A single number giving the approximate number of intensity depedent groups to consider. |
labs |
one or more character strings or expressions specifying the text to be written. If this string is not specified, by default the index of the vector ‘M’ will be used. |
output |
logical, defaulting to ‘FALSE’. If ‘TRUE’ a vector containning the index to the vector ‘M’ that are highlighted. |
