Re: [R] Creating a Date Field

Hi Phillip, Try this: as.Date(c("20180329","20180330","20180331"),"%Y%m%d") [1] "2018-03-29" "2018-03-30" "2018-03-31" Note that the format argument has to match the date format exactly. Jim On Wed, Sep 25, 2019 at 9:54 AM Phillip Heinrich wrote: > > The date is imbedded in the GameID characte

Re: [R] Creating a Date Field

You are not comparing your character date data with the format string. Specifically there are no spaces in your data but there are in your format string. Any characters in the format string that are not part of % date component specifications must be found in your data. On September 24, 2019 4:

[R] Creating a Date Field

The date is imbedded in the GameID character field so I created a date vector with the following code: ari18.test3$date <- substring(ari18.test3$GameID,4,11) And then created a new dataframe with just the Game ID and date vectors. The date field is a character as shown by the str() command. s

Re: [R] how to calculate True Positive Rate in R?

Hi Ana, Your minimum value in pvalR is very small and may be causing trouble. As the qvalue package seems to be in Bioconductor, perhaps posting to that help list would get an answer. Jim On Wed, Sep 25, 2019 at 1:48 AM Ana Marija wrote: > > Hello, > > I tried using qvalue function: > > libr

Re: [R] Loop With Dates

Just to add one more option (which is best probably depends on if all the same dates are together in adjacent rows, if an earlier date can come later in the data frame, and other things): df$count <- cumsum(!duplicated(df$Date)) Skill a cumsum of logicals, just a different way of getting the logi

[R] how to calculate True Positive Rate in R?

Hello, I tried using qvalue function: library(qvalue) qval_obj=qvalue(pvalR) pi1=1-qval_obj$pi0 but after running: qval_obj=qvalue(pvalR) Error in smooth.spline(lambda, pi0, df = smooth.df) : missing or infinite values in inputs are not allowed or qval_obj=qvalu
