thanks, this works, but is horribly slow (dim(f) is 766,950x2)

HI,
Not clear what you are trying to do:
set.seed(25)
df1<-as.data.frame(matrix(sample(1:40,20,replace=TRUE),ncol=4))
set.seed(15)
df2<-as.data.frame(matrix(sample(1:40,20,replace=TRUE),ncol=4))
do.call(rbind,lapply(list(df1,df2),`[`,c(2,4)))

Hi Janesh,
I'm going to ask you the same thing you were asked when you posted
this question on the r-sig-Geo list: What is data1? Please give us the
output of dput(data1), or make another example that we can reproduce.
Best,

Hello All,
I have a discontinuous dataset and I used spplot to plot the points.
I was wondering whether it is possible to show the legend of the plot as
color ramp. I saw that on continuous data. If anyone could tell me that
would be great.
Another thing I would like to know is how can we create
Hey everyone,
I just canât wrap my head around this problem: I got 2 Columns with 4
columns. They basically look like this:
1 2 3 4
⦠⦠⦠â¦
I want to merge the two CSVs into a two-column list, which should look like
this:
1 & 3 2 & 4
⦠â¦
⦠â¦
This is what I came up with so far
One way using `Reduce`:
set.seed(45)
grp <- factor(rep(letters[1:10], each=10)) # equivalent of your column x
# dummy data
df <- as.data.frame(matrix(sample(1:1000, replace=T),
ncol=length(levels(grp
# solution
Reduce('+', split(df, grp))/length(levels(grp))

Dear All,
I hope this is not too off-topic.
Essentially, I need to know if there is any R package which can help me
with a deformulation project.

Yes, Rui.
And, even more, the Tinn-R docs explain what to do and there's even a
Tinn-R menu item (R -->Configure --> Permanent) that should fix the
matter.

Hello,
This seems to be a Tinn-R question, to be addressed to its team, not to
R-Help. Anyway, since you're using R 2.12.1, maybe the error goes away
if you update your version of R.
Hope this helps,
