Dear Daisy,
You are making things too complicated. There is no need for a loop and a
nested if structure.
areaKM <- 7500
dat <- data.frame(
x = 1:30,
y = 31:60,
cellvalue = c(5, 6 , 7, rep(10, 10), rep(20, 17))
)#fake
if(areaKM > 15000){
treshold <- 30
} else {
treshold <- 5
}
n.cells
The corrected version is below. I found an error.
areaKM<-7500 #test for 7500 and 3
dat<-data.frame(x=1:30,y=31:60,cellvalue=c(5,6,7,rep(10,10),rep(20,17)))#fake
data
cells<-unique(as.numeric(dat$cellvalue))#find unique cellvalues
pres100km <- list() #empty list
for (ii in 1:length(cells)){
Hello,
I need to make a double clause in an if else/ next statement. I wrote a
single one fine but I could not make it work for two statements statements.
Please see the following example:
#Goals
#1)if size of area is greater than 15000 test that there are a minimum of
nrow() = 30,

Exactly. Just a matter of fixing the glm.fit Help page.

Hi:
I am trying to write code to run a simultaneous probit-tobit
model (Chappell, 1982) in order to quantify the determinants of
legislator voting behavior. I can't seem to find any background on this.
I have worked with code for simple logit and probit models, but this is

But
glm(1~1, family = gaussian) ## works. As does family = "gaussian"

The documentation for glm/glm.fit indicates that the family argument "can
be a character string naming a family function, a family function or the
result of a call to a family function".

Hello,
You are using a function in package nlme. You must first load the
package in your R session with the following instruction.
library(nlme)
Hope this helps,

This is a math question, not an R question. You cannot give numbers to asin
that are less than -1 or greater than 1 and get a defined answer.

Dear all,
I attempted to transform my data using "asin" but a WARNING message appears:
dat1$Abu.tr<-asin(sqrt(dat1$Abundance/100))
Warning message:
In asin(sqrt(dat1$Abundance/100)) : NaNs produced
What does it mean? Is it a problem? How can I solve this?
Thank you!

As Kehl pointed out, any linear function of the independent variable (speed)
will have the same squared correlation with the dependent variable (dist), but
only one linear function minimizes the squared deviations between the fitted
values and the original values. The equation you are using is o
