Hi all,
I am hoping someone can help me out with this:
If I have dataframe of years and ages and the first column and first row
are filled with leading values:
Df<-age1age2age3
Yr1 1 0.4 0.16
Yr2 1.5 0 0
Yr3 0.9 0 0
Hi all,
I am having a problem getting my fucntion to work correctly.
Here is my problem.
I have three ages: Nage<-c(1,2,3)
I have an weight matrix: Wt<-c( 0.04952867, 0.23808432, 0.34263880)
I have an age schedule of maturity: Mat<-c(0,1,1) where 0 is not mature,
and 1 is mature

Hi all,
I have a question about expression.
In a figure I want to include the term D*obs with the star as as
superscript and obs as subscript. I have even just tried to get the
star to be superscript.
The code I tried was
text(Dstar+7,120,expression(paste({}D,^*))), but that doesn't work and

Hello everyone,
I have a function here that I wrote but doesn't seem to work quite
right. Attached is the code. In the calib funcion under the for loop
Bt[i+2]<-(1-m)*Bt[i+1]+Rt[i]*Rerr-Ct[i+1] returns NA's for everything
after years 1983 and 1984. However the code works when it reads
Bt[i+2]<-

Is
X1 = which(duplicated(x))
x[-X1,]
or
x[!duplicated(x),]
or
subset(x,!duplicated(x))
what you're looking for? Remember that which() will always return
indices, so negating them

Hello everyone,
I have a large dataset (x) with some rows that have duplicate variables
that I would like to remove. I find which rows are the duplicates with
X1<-which(duplicated(x)). That gives me the rows with duplicated
variables. Now, how can I remove just those rose from the original data

Hello all,
I hope someone can help me with this.
I have function that calculates two values based on input data. A
simple example follows:

y<-vector()
p<-vector()
for(i in 0:length(rangit)){
y[i]<-x+s[1]+rangit[i]

I am trying to great a new column of effort data from an existing vector
of gears used.
It is a simple code where
effort[Gear==300]=(DIST_TOW*7412)
effort[Gear==301]=(DIST_TOW*7412)
The code appears to work for some of the data but fails for others and
inserts a NA value
