I have never used that function, but I know that with read.csv() you can do
the following to select only the columns you want:
chosen_vars <- read.csv("Workbook1.csv", header=T)[c("variable1",
"variable3")]

Great. Then, if one is interested in selecting the second row of a variable
(from a unique id), something like this should work:
aggregate(value ~ id, data = dat, FUN = function(x) head(x, 2)[2])
Thanks, Michael and Dennis!

I know that read.spss in the foreign library will bring the data into R but
can I choose to important only chosen variables from the SPSS dataset to R?
Thanks for your help.

Hi all,
I'm having a problem restructuring my data the way I'd like it. I have data

Hello all,
I'm having trouble creating an adjacency matrix.
Basically, I need to turn the following distance matrix into an adjacency
matrix based on whether values are >1.5 or not. If they are >1.5, then the
returned value should be 0. If they are =<1.5, then the returned value
should be 1.

Hi:
The head() function is helpful here:
(i) plyr::ddply()
library('plyr')
ddply(dat, .(id), function(d) head(d, 1))
id value
1 1 5
2 2 4
(ii) aggregate():
aggregate(value ~ id, data = dat, FUN = function(x) head(x, 1))
id value
1 1 5
2 2 4
The formula version of aggreg
Why would that be preferable to dropping the variables after importing the
whole dataset?

I think that's in general a trickier question:
If you are absolutely certain your id's are in blocks and that there are at
least k of them, it would perhaps work to do a manual adjustment of the
indices:something like
# UNTESTED
with(dat, dat[which(!duplicated(id)) + k - 1, ]) # where k is the
wh
dat <- data.frame(id = c(1,1,1,2,2), value = c(5,6,7,4,5), value2 =
c(1,4,3,3,4))
with(dat, dat[!duplicated(id),])

Hi,
I am trying to select the first row of a variable with data in long-format,
e.g.,
# sample data
id <- c(1,1,1,2,2)
value <- c(5,6,7,4,5)
dat <- data.frame(id, value)
dat
How can I select/subset the first 'value' for each unique 'id'?
Thanks,
AC

i generally work round this problem by increasing the margins to leave more
room for labels ( eg with par( mar=c(6, 4, 4, 2) + 0.1 ) ) and then put axis
labels in using something like title(xlab='x axis', line=4). Giving xlab="" in
plot() is a simple way of suppressing the default xlab.

Dear all,
this is more a math-related question, but probably can help me nevertheless:

Furthermore assume that I know the Pearson Correlation Coefficient between A

Is there some way to determine cor(C,A) and c
