I am having some trouble with this code. So far I have:
yes<-0
no<-0
sample<-20000
mean<-(10/12)
LowerBound<-LB
UpperBound<-UB
LB<-(mean-2)*sqrt(20/1872)
UB<-(mean+2)*sqrt(20/1872)
for(i in 1:sample){
sample<-rbeta(10,10,2)
LB<-(mean-2)*sqrt(20/1872)
UB<-(mean+2)*sqrt(20/1872)
}
But I am getting the error of
Error in eval(ei, envir) : object 'LB' not found
You have things out of order. you are defining LowerBound as the value of LB but LB is not defined until later as LB<-(mean-2)*sqrt(20/1872)
yes<-0
no<-0
sample<-20000
mean<-(10/12)
LB<-(mean-2)*sqrt(20/1872)
UB<-(mean+2)*sqrt(20/1872)
LowerBound<-LB
UpperBound<-UB
for(i in 1:sample){
sample<-rbeta(10,10,2)
LB<-(mean-2)*sqrt(20/1872)
UB<-(mean+2)*sqrt(20/1872)
}

When I am running the following lines, there is an error saying Error in toSrting(m) : could not find function "toSrting". I have no idea what happened since toString usually works well but not here:
m <- 1
for(m in 1:60000){
toSrting(m)
paste("trainxr", m) <- raster(trainxr[m,,])
strtoi(m)
m <- m + 1
}
Thank you for your help.
I've never used R but I think string is spelled wrong.

I have the following code:
unlink(dir, recursive = true)
And I am getting this error message:
* object 'true' not found
What is the cause of the error message?
Boolean constants are in all caps - use TRUE/FALSE. Other languages usually define them as true/false. So the correct code would be:
unlink(dir, recursive = TRUE)

I am not sure why I cannot do write the following code.
as.Date(20110505, %Y%m%d)
I receive the error given in the title. Can anyone help me out?
It should be string with the format also in quotes
as.Date(as.character(20110505), "%Y%m%d")
#[1] "2011-05-05"

This is the R command I used to create a decision tree,
k <- C5.0(data1[1:16000,-32],as.factor(data2{1:16000,32])
but this output I get for error:
Error: unexpected '{' in "k <- C5.0(data1[1:16000,-32],as.factor(data2{"
Did I forget a bracket? I couldn't figure out why
Try
k <- C5.0(data1[1:16000,-32],as.factor(data2[1:16000,32]))
You used { instead of [ at the end and you also forgot to include another ) to wrap up your C5.0 function.

I have an error
> for (i in 1:(cutoff_size-1)){work$group[i]=rep(c(0,1),c([i]-1,cutoff_size-[i]-1))}
Error: unexpected '[' in:"for (i in 1:(cutoff_size-1)){work$group[i]=rep(c(0,1),c(["
'cutoff_size' is numeric.
How can I solve this problem?
for (i in 1:(cutoff_size-1)){work$group[i]=rep(c(0,1),c(i-1,cutoff_size-i-1))}
this is probably what you're looking for.
[] are used to refer to position in array/data table/list.
If you're using it in a mathematical operation, you do not need the [] around the i.
