[R] Root Dir for OpenCpu files

I have opencpu (single server) up and functioning. My first function will open a dataset from a csv file stored on my hard drive. Where should I deploy the csv file? (I tried my apps www directory, but it doesn't work) In sum: within an opencpu app, where do I deploy a file so that this line of

Re: [R] Problem in conversion of regulate time series and forecasting using Date Time [Timestamp values]:R

gg$timestamps <- as.POSIXct(as.character( gg$timestamps ) ) Factors are integers with the appearance of character data, so you are converting the integers to POSIXct. I usually try to avoid letting R automatically convert character data to factors, e.g. using stringsAsFactors=FALSE in read.csv

Re: [R] Problem in conversion of regulate time series and forecasting using Date Time [Timestamp values]:R

Hi Jim, Thank you for the reply. 'gg.ts' is actually the object name of the time series I am using here. Also I have changed my timestamp class from factor to POSIXct (gg$timestamps <- as.POSIXct(gg$timestamps, format = "%Y-%m-%d %H-%M-%S") . When i plot this time series on graph, the x axis

Re: [R] survival package can't find Ccoxfit6

Since my coding philosophy is "why compute something that is not needed" I don't have timing data comparing coxph.fit to the stripped down version. I will try to come up with a test suite. I do work under Linux (the initial Windows output was because I had both 3.3.1 and 3.4.0 on that

Thank you Drs. Therneau and Murdoch. "Why not use coxph.fit?" -- My use case scenario is that I needed the Cox model coefficients for resampled data. I was trying to reduce the computational overhead of coxph.fit (since it will repeated a large number of times) by stripping all the parts that

Re: [R] Problem in conversion of regulate time series and forecasting using Date Time [Timestamp values]:R

Hi Dhivya, I'm not that familiar with the "gg.ts" function, but you are passing character values to the "frequency" and "start" arguments. If there is no automatic conversion to numeric values, that would cause the error. Similarly, your "timestamps" variable may have been read in as a factor,
