Hi Greg,
I am sketchy on a few details of C, but does something like this work
for you? I just created C1 (renamed because C() is a function) with
two columns the first corresponding to A and the second to B. Then I
just used the first column to select elements of A and the second to
select elem
Hi,
Suppose I have array A with 100 elements all filled in with "N/A". Array
B has 25 elements with actual values. Lastly, I have array C that
provides a map of where to put the elements from array A into array B.
Thus C would say put element 1 from B into element 3 from array A.
I realize
Thanks Jorge,
That is what I was looking for.

Hi James,
Take a look at the "recode" function in the "car" package. It might be
useful in this case.

Hello,
I am trying to map a factor variable within a data frame to a new variable
whose entries are derived from the content of the original variable and there
are fewer factors in the new variable. That is, I'm trying to set up a
surjection.

Hi,
You could have a look at the sp-package, it provides R-classes for
spatial data. In addition, it also provides very nice plotting
facilities. To read your data into these sp classes you can use the
rgdal package. There is also an R mailing list specifically for
geographic data (r-sig-geo)
Hi folks,
I'm just learning how to use maps. As an initial foray, I'm mapping the
states that have "duty to retreat" (blue) and "stand your ground" (red)
self-defense standards. Here is my extremely naive script:
dtr <- c('alabama', 'arizona', 'conneticut', 'delaware', 'dist of columbia'
, 'hawa
It is relatively easy to do a small function for this in R:
a) select the desired width for your border
b) through a fix number or through the use of pretty(), establish the
number of rectangles you want along your border.
Then e.g., you can use rect() you build the sequence of black-white
