...k of presenting something that has been shown before, below I demonstrate how a column in a data frame can be dropped using a wild card, i.e. a column whose name starts with "th" using nothing more than base r functions and base R syntax. While additions to R such as tidyverse can be very helpful, many things that they do can be accomplished simply using base R. # Create data frame with three columns one <- rep(1,10) one two <- rep(2,10) two three <- rep(3,10) three mydata <- data.frame(one=one, two=two, three=three) cat("Data frame with three columns\n") mydata...

You could have negative indices. There are two ways to do this. 1) provide a large offset. Offset <- 30 for (i in -29 to 120) { print(df[i+Offset])} 2) use absolute values if all indices are negative. for (i in -200 to -1) {print(df[abs(i)])} Tim -----Original Message----- From: R-help <r-help-bounces at r-project.org> On Behalf Of Peter Dalgaard via R-help Sent: Monday, April 22, 2024 10:36 AM To: Rolf Turner <rolfturner at posteo.net> Cc: R help project <r-help at r-project.org>; Hans W <hwborchers at gmail.com> Subject: Re: [R] x[0]: Can '0' be...

I installed R 3.4.2 (Windows) and noticed that 30 folders are under my R_HOME/library folder. I assume all of these are R base packages. Is this correct? Where can I see a list of current R base packages? Also; are R base packages also in CRAN? and are these packages updated only when a new version of R is released or can the be updated at a different time? Thanks [[alternative HTML version

...t I know of to having unused space in a matrix is the amount of memory it takes.

Dear R Fellows, I Have a dataset( data1) with 2 columns of date showing a class of factor. How to convert them to date? Then compare them, keep the greater date only in a new column. Using as.Date to change the class to Date but the data becomes NA. Much Thanks COL1 COL2 Apr-16 1-Nov-16 May-16 1-Nov-16 Jun-16 1-Nov-16 Jul-16 1-Nov-16 Aug-16 1-Nov-16 Sep-16 1-Nov-16 Oct-16 1-Nov-16
