Hi List Members,
This is a very stupid problem but I am not able to know what the solution
can be.
I am trying to run a query like below
*Program Flow :*
1. a <- data.frame(table( cut( Sys.time() + seq(0,82800,3600), "60 mins")
)) # It generates the 60 minute intervals. Thanks David
2. b <- data.frame(a$Var1)
# To extract only First Column i.e. Var1
3. class(b)
# checking class
4. b[1:1,1:1]
# Trying to access the first row and the
problem starts.
2. b <- Sys.time()+ 5*60
# 5 minute interval increase
3. ifelse(b[1:1,1:1] *"<" *Sys.time()+5*60,rnorm(1,0,5),Sys.sleep)
Error: unexpected string constant in "ifelse(b[2:2,1:1] "<"
My only aim is to run "ifelse" for checking whether the program is running
or not.Please help
*Data :*
a <- structure(list(Var1 = structure(1:24, .Label = c("2012-09-19
16:40:00",
"2012-09-19 17:40:00", "2012-09-19 18:40:00", "2012-09-19 19:40:00",
