Error in R script with lubridate package

Question

Hello AK,
I have corrected the code as you can see below but I am experiencing some issues :  
Error 0063: The following error occurred during evaluation of R script:
 ---------- Start of error message from R ----------
 'to' cannot be NA, NaN or infinite
 'to' cannot be NA, NaN or infinite
 ----------- End of error message from R ----------
****the code***
## Map 1-based optional input ports to variables
winData1 <- maml.mapInputPort(1) # class: data.frame
install.packages("src/ggplot2_1.0.0.zip", lib = ".", repos = NULL, verbose = TRUE)
install.packages("src/lubridate_1.3.3.zip", lib = ".", repos = NULL, verbose = TRUE)
library(ggplot2, lib.loc=".", verbose=TRUE)
library(lubridate, lib.loc=".", verbose=TRUE)
withCallingHandlers({
    print(dmy_hm("01/01/2002 00:00"))
    print("done")
}, warning=function(w) {
    message("handled warning: ", conditionMessage(w))
    invokeRestart("muffleWarning")
winData1$date_time<-dmy_hm(paste(winData1$DATE, winData1$Time))
ggplot(winData1, aes(date_time, AnemSD40aMS)) + geom_point() + geom_line()
# Select data.frame to be sent to the output Dataset port
maml.mapOutputPort("winData1");
Pls I need your help on this.
Thank you.

I'm not sure what the purpose of your withCallingHandlers() call is, you are not guarding any code that is useful - if it happens, it'll also happen outside and you won't catch it. If it doesn't happen, you don't need it.
There is no need to install.packages() ggplot2, it's preinstalled - just use library(ggplot2)
Can you please post the full output log? it looks like something in your script isn't the size/shape you think it is.
If you str(winData1) in your script before doing the above we can help by looking at the structure
Regards,
AK
