Depending on your OS, there might be a better chance of success with


install.packages("ggplot2", dependencies=TRUE)

The Linux install process doesn't need this but the binary install on MacOS or 
Windows may need this to prevent the sort of error message that was offered.

library(ggplot2)

An alternative
install.packages("tidyverse")
library(tidyverse)

The first only installs ggplot2. The alternative installs a bunch of other 
stuff as well.

Hi there,

I am finally getting to some material I had problems with in university, where I was 
introduced to R - one of those that because of time constraints, I had challenges 
figuring out, particularly because I decided long ago on using Fedora Linux. The book, 
"Understanding Statistics Using R" by Andy Field et. al., says to install 
ggplot2 into R and the version of R that the dnf command installs will neigher install 
this package nor 'scales'. The result I get is below, and I attempted installing the 
packages via the tar command, and that neither worked, and I attempted
library("ggplot2") and R said the package was unavailable. What can I do to 
move forward?

Thanks,

Richard

[R] complicated time series filtering issue

2022-04-04 Thread Cade, Brian S via R-help 
Hello:  I have an issue with filtering in a time series of animal growth data 
that seems conceptually simple but I have not come up with effective code to 
implement this.  I have temporal sequences of lengths by individuals and I want 
to retain only those data that are >10 days apart sequentially within an 
individuals records.  I can readily compute intervals between successive dates 
by individual using data.table() and its by = INDIVIDUAL functionality.  See 
example data for one individual below.  But what currently eludes me in 
processing this is how to recognize for example that deleting the 2nd and 3rd 
rows is required because the totality of their time interval is 9 days, 
deleting 8th record with 4 days is required,  deleting 17th record with 1 day 
is required, deleting 22nd and 23rd records is required because their sum is 2 
days, but we do not delete 24th record of 10 days because the sum of previous 2 
records deleted and this one is now 12 days.  Each individual can have very
  different patterns of these sort of sequences.  These sequences are easy to 
look at and determine what needs to be done but writing effective code to 
accomplish this filtering seems to require some functionality that I am 
currently missing.

Any suggestions would be greatly appreciated.
