Hi, list experts

I am totally a new user of the R package. I just tried to use qcomhd, but
it gives me an error alarm, as below.

qcomhd(RT1, RT2, q = seq(.1, .9, by=.1))
Error: could not find function "qcomhd"

Then I try to install it, however, it seems that I am not able to install
it. Also, in my screen, some chaos characters appear. I do not know the
reason.
Installing package into
?:/Users/kh645-admin/Documents/R/win-library/3.1?(as ?ib?is unspecified)
Warning in install.packages :
  package ?comhd?is not available (for R version 3.1.2)

A second question is to closely follow this thread *[R] Vincentizing
Reaction Time data in R*

Gabriel, have you find a good solution for your searching? I am also
interested in the vincentizing RT method. Either in R or Matlab would be
okay for me.

Thanks in advance,
J

I an not aware of any function or package named qcomhd in base R or in the CRAN contributed packages, nor did it turn up when I went searching for it there, so your failure to access it seems unsurprising.

Google does find some references to a Github package called WRS that supposedly contains such a function, but the reason given for not distributing it on CRAN is simply that the package does not contain full documentation. This rather pathetic excuse points out that such a package is likely to be very unhelpful for any new user of R. I would suggest that you learn a bit more about using R before diving into such murky waters, but if you want to push forward you will need to use a search engine and perhaps make email contact with the package author if you need help.
