DF1 is a data frame. I am suspecting there might be non date value
in that column. My question is how to remove a non date values from
that field.
example if Alex152 has 12253,. This value is not a date format.

A very dirty solution.
I hope someone can give a better solution:
library(ggplot2)
set.seed(1)
df <- expand.grid(g = factor(1:4), f = factor(c("a", "b", "c")))
df <- df[-1, ] # some factors are not present in certain groups
df$v <- runif(nrow(df))
library(dplyr)
df <- df %>% arrange(g, desc(v))
Hi Jeff
I have seen the seq_along function but never knew the what or why of it. Your

Thank you for enlightening me. Carl Sutton

Have you ever used the seq_along() function?
If you want to delegate the decision of how many elements you want to process
to some earlier point in your (or someone else's) code, then the most logical
way to create a result vector that is the same size as some input vector, even
if that vector
Hi
just messing around today and am now perplexed by the seq argument
"along.with".
Please, I am just just seeking some knowledge here. Obviously I missed a point
and would like to know what it is.
seq(1,10,length.out = 2) makes sense
seq(1,10,by = 2) makes sense
seq(1,10, along.wi
Hi,
I need to bars to display in order based on the values of "v" within each
group "g". Is this possible?
library(ggplot2)
set.seed(1)
df <- expand.grid(g = 1:4, f = factor(c("a", "b", "c")))
df <- df[-1, ] # some factors are not present in certain groups
df$v <- runif(nrow(df))
ggplot(df, aes(
