I am using Windows XP and R 2.3.1.
During my lastest session I updated my packages and now when I try to start
R 2.3.1
I get the following error message:
Fatal error: unable to restore saved data in .RData in an error window and
Error in loadNamespace(name): there is no package called 'nlme' in th
I think I need to clarify a little further on my original question.
I have the following two rows of data:
mydat<-data.frame(d1=c(3,5),d2=c(6,10),p1=c(.55,.05),p2=c(.85,.35))
>mydat
d1 d2 p1 p2
1 3 6 0.55 0.85
2 5 10 0.05 0.35
I need to optimize the following function using optim for each row
I have defined the following function:
fr<-function(x) {
u<-x[1]
v<-x[2]
sqrt(sum((plnorm(c(3,6),u,v)-c(.55,.85))^2))
}
which I then solve using optim
y<-optim(c(1,1),fr)
> y$par
[1] 1.0029771 0.7610545
This works fine.
Now I want to use these two steps on a dataframe:
mydat<-data.
If I have two matrices:
> a<-matrix(1:5,ncol=1)
[,1]
[1,]1
[2,]2
[3,]3
[4,]4
[5,]5
> b<-matrix(1:50,ncol=10)
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,]16 11 16 21 26 31 36 4146
[2,]27 12 17 22 27 32 37 42
