sapply( ) a loop function
Hello R-universe...
I am having trouble writing a function which contains a loop so I can sapply() it to a list of data frames
Each data frame has 241 observations of 15 variables. My loop takes a random sample of one row until the 40 consecutive rows after the sample have a d2p(variable) sum greater than 5.
here is my loop code (it works fine when applied to a 241 observation data frame):
n<-241
test<-0
while(test<5){
i<-sample(1:n-40,1)
x<-my.data.frame[seq(from=i, to=i+40),]
test<-sumx[,"d2p"],na.rm=TRUE)
}; i ; test
I need this...

Select Random Rows from a dataframe
Hi all,
I have a dataframe of behavioral observations from 360 fish, each with 241 observation points(rows), which looks like this:

1 1 3 1 1 1 1 1 NA NA 0.0 0.000 NA NA 5.169 9.617

applying a loop to multiple dataframes
Hello again R-folks,
I'm trying to apply a loop to multiple data frames and then organize the data in a manageable form. I have the code for my loop figured out (thanks to help from this list)...it runs up to 2000 iterations of a "while" loop until it finds a 40-row "d2p" column sum >5
n<-nrow(dsub.f1)
test<-0
for(k in 1:2001){
if(k>2000){
break} #stops after 2000 iterations
else{
while(test<5){ #continues unti sum>5, or 2000 iter.
i<-sample(1:n-40,1)
x<-dsub.f1[seq(from=i, to=i+40),]
test<-sum(x[,"d2p"],na.rm=TRU...
