Hi all,
I recently posted a problem concerning shaded regions with quantmod
package. More precisely,
I used the function addTA with a boolean vector: for example
addTA(vecB,col="green",border=NA,on=-1)
where vecB is the boolean vector.
In some cases, the shading result was not conform
with the boolean vector. I checked the R source program, and more
precisely the function chartTA() in TA.R file. So in the function
chartTA, it seems that there is a mistake with the vector x.pos.
the vector is given by
x.pos <- 1 + spacing * (1:length(x.range))
and it seems that this vector should be
x.pos <- 1:(spacing*x.range[2])
So I hope this indication would be relevant for people who work on
the improvements of this package.
Best regards.
O.
