Sequences
Hi,
I am trying to make a sequence and am using a for loop for this. I want to
start off with an initial value ie S[0]=0 then use the loop to create other
values. This is what I have so far but I just keep getting error messages.
#To calculate the culmulative sums:
s<-rep(0,207) #as this is the length of the
vector I know I will have
s<-as.vector(s)

turning list into vector/dataframe
Hi,
I have used this command :
resamples<-lapply(1:1000,function(i) sample(lambs,replace=F))
resamples2<-lapply(resamples,Cusum)
to get a list of 1000 samples of my data. The function Cumsum is defined as
follows:
Cusum<-function(x){
SUM<-cumsum(x)-(1:length(x))*mean(x)
min<-min(cumsum(x)-(1:length(x))*mean(x))
max<-max(cumsum(x)-(1:length(x))*mean(x))
diff<-max-min

converting numeric into character strings
Hi,
Im trying to put some numbers into a dataframe , I have a list of numbers
(change points in a time series) like such
[1] 2 11 12 20 21 98 99
but I want R to recognise this as just a character string so it will put it
in one row and column, ideally I want them seperated by commas so I would
have for example
Person Change points (seconds)

Linear model, finding the slope
Hi
for some data I working on I am merely plotting time against temperature for
a variable named filmclip. So for example, I have volunteers who watched
various film clips and have used infared camera to monitor the temperature
on their face at every second of the clip.
The variable names I have used are Normalised ( for the temperature) and
Frame (for the time in seconds).
So I have fitted a
