[Solved] data type conversion in R [closed]

by


Seems your code needs to be cleaned up a bit:

  if(lastFlag!=1){
  lastDay <<- rawData$Date[nrow(rawData)]  # last complete day
  rawData <<- subset.data.frame(rawData,rawData$Date < lastDay)
  }

I think the “rawData” could be an empty dataframe here but not be checked;

Let’s suppose:

rawData <- data.frame(x=c(), y=c())
tProcRows <- 100

So: 

tProcRows <- tProcRows + as.numeric(row.names(rawData)[nrow(rawData)]) 
print(tProcRows)

Output:

numeric(0)
