I would argue that your Wilcoxon test is meaningless. For all four datasets,
the first data column has no overlap whatsoever with the second data column.
All Wilcoxon Ws are 0. The BIZARRE behavior may be that the test tries to
interpolate what the p value for W of 0 would be given your sample
The following link may be of interest. It shows a way to use gsub, but have it
automatically applied while reading the data in rather than converting after:

If you are willing to prepend a step then you could:
1. Create an empty plot using your data and type='n' (or just plot the data,
the points will be overwritten), you may want to set the asp argument, or
explicitly do the xlim and ylim arguments.
2. Add the graphic using the rasterImage
hi, im a new in R and this forum, so if there is something disturbing u, im
gonna do it better.
by the way, where can i see the FAQ 7.21?? thanks..

This sounds like what is called domains in survey sampling (possibly other
names, but that is what I learned it as). The idea is that you take a random
sample (or the population) then ask a question to determine which domain the
subject is in, then ask the question of interest in the domain of

here i hav a question, how can i save the value of a list to a vector or a
matrix? say,
i have a list (data1) and a vector or a matrix (data2).
if i made like this,
data2 - as.vector(data1)
it does not change anything, the data2 is still a list.
what i want to do is to
If the list is simple enough, then you probably want the unlist function,
otherwise you will probably need to use the sapply function to grab and/or
process the important pieces in each list element.

Where are you stuck? A question without reproducible code or demonstrating
own effort is much less likely to receive a response.
Best,

There is a function interpequal in the trip package that provides a
way to generate new points equally spaced in time between irregular
track points. Obviously this can only be approximate depending on the
spacing you want. The function also maintains the input points without
change. This was used
Thats perfect, thank you!

Dear Daniel and Sarah,
Thanks you for your rude replies .
The script that I provided was only an example and to illustrate the
problem. It makes perfectly sense to use the Wilcoxon test on my datasets.
However, you replies were nonsensical, since you could not solve the problem
but rather just
