how to change data type in data frame?
Hi, list,
suppose i have such a data frame:
trash <-
data.frame(cbind(seq(1:5),c('a','a','b','a','b'),c('b','a','b','b','a')))
names(trash) <- c('age','typeI','typeII')
and I want to change all 'a's to be 0 and 'b's to be 1.
temp <- as.matrix(trash)
temp[temp=='a'] <- 0
temp[temp=='b'] <- 1
temp <- data.frame(temp)
the problem was that temp$typeI and temp$typeII were still factors,
whereas I want numeric type....

Error with adehabitatHR and kernelbb
...he net and it happened to only one person and there was no answer to his post.
Someone could help me?
## commands
BBtraj <- list()
for (i in 1:(nrow(loc@data)-1)) {
BBtraj[[i]] <- kernelbb(as.ltraj(loc@coords[i:(i+1),], date=loc@data$time[i:(i+1)], id = as.character(loc@data$id[i:(i+1)]),
typeII = TRUE), sig1=as.numeric(as.character(loc@data$sig1[i])), sig2= 5, grid = 1000)
}

linear mixed model with nested factors
...ith either
lme or lmer and I am having no luck obtaining the same results as Minitab.
Here is Minitab's code:
MTB > GLM 'count' = site year replicate(site year) site*year;
SUBC> Random 'year' 'replicate';
Can you tell me how to code this in R?
The settings are typeII, Tukey, 95%confidence interval, but I know how to
set those in R.
I have basic R skills and I've worked with this on and off for several
days, and have also consulted some people with basic R experience, but
nobody can get it to work as it seems to be a bit complex. I'd prefer to
use R rat...

How to assign vector value as object name
...("tr1.",i,sep="") # extends
vector of names
}
for (k in 1:20) {
assign(nam_ltraj[k], as.ltraj(xy=nam_xy[[k]], date=data.mov$DATE,
# assign an object name to an ltraj object with animal specific data
id=nam_id[[k]], burst=nam_burst[[k]], typeII=T,
slsp=c("remove","missing")))
}
Any input on how to solve this is highly appreciated!

Trouble with first passage time analysis using adehabitatLT
...g the ltraj object from a dataset.
/test<-read.table("~/Desktop/R_Directory/test.txt",header=TRUE)
attach(test)
library(adehabitatLT)
xy<-test[,c("x","y")]
date1<-as.character(date)
date<-as.POSIXct(date1)
fit1<-as.ltraj(xy,date,id=test$name,burst=name,typeII=TRUE)/
from here things start to get fuzzy
1)
Instead of following the basic expression,
/fpt(lt, radii, units = c("seconds", "hours", "days"))/
the sample code on the tutorial expressed fpt as,
/fpt(lt, seq(300,1000, length=30))/
But as far as I can tell this c...
