Creating binary variable depending on strings of two dataframes
Hi,
consider the following two dataframes:
x1=c("232","3454","3455","342","13")
x2=c("1","1","1","0","0")
data1=data.frame(x1,x2)
y1=c("232","232","3454","3454","3455","342","13","13","13","13")

Reshape from long to wide format with date variable
Hi,
I need to reshape my dataframe from a long format to a wide format.
Unfortunately, I have a continuous date variable which gives me headaches.

> date=as.Date(c("1997-09-28", "1997-10-06", "1997-11-04",

Loop with random sampling and write.table
Hi!
I need to perform this simple sampling function several hundred times:
x1=as.character(rnorm(1000, 100, 15))
x2=as.character(rnorm(1000, 150, 10))
y1=as.data.frame(x1,x2)
sample1=as.data.frame(sample(y1$x1, 12, replace = FALSE, prob = NULL))
sample1
write.table(sample1, "sample1.txt", sep=" ",row.names=F,quote=F)
My knowledge of loops is quite low. How can I produce 100
