[R] Bias-corrected percentile confidence intervals

Hi folks, I'm trying to estimate bias-corrected percentile (BCP) confidence intervals on a vector from a simple for loop used for resampling. I am attempting to follow steps in Manly, B. 1998. Randomization, bootstrap and monte carlo methods in biology. 2nd edition., p. 48. PDF of the

[R] string pattern matching

Hi Folks, Is there a way to find "x1 + x2 + x3" given "x1 + x3" as the pattern? Or is that a ridiculous question, since I'm trying to find something based on a pattern that doesn't exist? test <- c("x1", "x2", "x3", "x1 + x2 + x3") test [1] "x1" "x2" "x3" "x1 + x2 +

[R] Lubdridate: subset based on hour and minute

Hi folks, I must be missing something obvious/painfully simple here How do I subset a time vector based on hours AND minutes? So, in this example, I want all time greater than 10:00, i.e., 10:30 and 11:00. I'm working with lubridate which separates the hours and minutes into separate slots.

R Helpers, I would like to extract the entire word beginning with "BT" (or "BT-") and not any thing else in the string. Or, I would like to extract from BT up until the next space. test <- data.frame(x = c("abc", "Sample BT-1501-2E stuff", "Bt-1599-3E stuff")) test So, from test$x I would like

[R] Split strings based on multiple patterns (plain text)

Hopefully this looks better. I did not realize gmail default was html. I have a dataframe with a column that has many field smashed together. I need to split the strings in the column into separate columns based on patterns. Example of a string that needs to be split: ugly <- c("Water temp:14:

Hi all, There are many R help posts out there dealing with slashes in gsub. I understand slashes are "escape characters" and thus need to be treated differently, and display differently in R. However, I'm still stuck on find-replace problem, and would appreciate any tips. Thanks! GOAL: replace

Re: [R] R STUDIO crashing

I had this problem as well, a lot, and it was frustrating and I did not find much reference to it online. I believe it occurs after you run a plot and then make the plotting window too small for R studio to redraw the plot. Then when run a line of code, it never runs or appears to be running
