I posted this on SO, got no response. Sorry about cross-posting,
but atleast I would like to know if I am understading something totally
wrong
I am using a `glmulti` wrapper for glmer (binomial) and the `summary` is:
`This is glmulti 1.0.7, Apr. 2013.
Length Class Mode
0 NULL NULL`
DT<-data.frame(time=c(0,1,5,24,36,48,72),DV=seq(0,60,10))
time DV
10 0
21 10
35 20
4 48 30
5 84 40
6 96 50
7 120 60
You want to add 24 to values that are >=24 in 'time'
DT[DT$time>=24,'time']<-DT[DT$time>=24,'time']+24
time DV
10 0
21 10
35 20
4 48 30
5 60
DT = data.frame(x=rep(c("a","b","c"),each=3), y=c(1,3,6), v=1:9, w=3:11,
z=LETTERS[1:9])
If I understand you right, and you want to select all rows where v>3 and
W<10
with(DT, DT[which(v>3 & w<10),])
x y v w z
4 b 1 4 6 D
5 b 3 5 7 E
6 b 6 6 8 F
7 c 1 7 9 G
you can use colSums, rowSums on th
Hi Michael
thanks! That was the option if I kept it an array. The list format with $
sign since it leaves me feeling that the names are there and can be easily
accessed. Why would you rather not use the $ sign?
I use R-Studio and there names can be selected from a drop-down list, I have
found it
I have an 4D named array (the result of recast() on a dataframe) and would
like to convert it to a list with the names retained.
Example:
>my.df<-expand.grid(name=c("Alf","Que"), month=c("May","Jun"),
year=c("2011","2012"))
>my.df$tmax<-sample(15:20,4)
>my.df$tmin<-sample(10:15,4)
>my.df.melt=mel

let me try rephrase my previous post this way. I have a distribution of
points ( with cords) and I want to select only or two points that fall
within a buffer distance from each point. I guess there should be some way
to do this in R. Can someone help or suggest where I might find a solutio
Hi all
I am pretty new to R and would like some help concerning subsampling my
data.
I have got locations of species presence that are clustered in some regions
of my study area. using this for habitat modelling produces overfitting the
denser areas. I would like to subsample the presence locatio
