[R] Compare data in two rows and replace objects in data frame

[R] create new column by replacing multiple unique values in existing column

be substituted according to their unique values e.g "A1" will be "1", "A2" will be "2" and so on (this is only a part of a large table). It would be better if I could change all unique values in dat1 to numbers 1:unique(n). if not then how do I change all

[R] Physically extracting P-value from TukeyHSD test output

Hey, I have this TukeyHSD output from which I would like to extract only the P-values (p adj, last number). The problem is that the test output is a character list. How can I "break" this sentence to separate the Pv? Tukey multiple comparisons of means 95% family-wise confidence level Fit:

[R] compare two rows in same column in data farme

[R] Conditional error bars

How can I condition any error bar function that use the arrows() function, such as 'CI.plot' (see example below) or 'error.bars', to draw only upper error bar (upper CI) if the bar value (mean) is positive and the lower error bar (lower CI) if bar value is negative? CI.plot <- function(mean, se,le
