vec1# dataset

?vec1[names(vec1)>1820]
head(vec1[names(vec1)>1820])
?# 1821?? 1822?? 1823?? 1824?? 1825?? 1826

[R] extract values

Look at your data. You do not want values greater than 1820. There are none.
You want values with NAMES greater than 1820.
> x1 <- x[as.numeric(names(x)) >1820]
> x1

[R] extract values

Data in x is never > 1820:> summary(x)   Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
 0.8465  1.2890  1.5660  1.5710  1.8050  3.4340

And your object is a vector: trying to extract the first column with
x[,1] is meaningless, because x has no dimensions.> dim(x)NULL

It looks to me as if you want to extract values of x where the *names*
are > 1820, but the names are character, so maybe:

x1 <- x[as.numeric(names(x)) > 1820]

is what you're looking for.

[R] extract values

Hello,

I don't understand. Your object is a vector, with a dim attribute, so 
x[, 1] is meaningless. And all the values are less than 1820:

any(x > 1820)  # FALSE

Given the names attribute of your data, is it the values of x 
corresponding to names greater than 1820? If so, try

y <- as.numeric(names(x))
x[y > 1820]


Hope this helps,

Rui Barradas
