Mixing
Group clause in ggplot loop
I would like to put a ggplot in a loop. The loop is to go over multiple columns. I managed this without the group clause in the aes command with the help of an udf I found on another thread:
How do I combine aes() and aes_string() options
# Necessary for use of BOTH aes and aes_string
`+.uneval` <- function(a,b) {
`class<-`(modifyList(a,b), "uneval")
}
# Create list of column names
columns = as.character(c("quantity_actual", "price_sale", "quantity_corrected"))
# Loop through the columns
for (i in columns)
{
print(
ggplot(demand, aes(x = date) + aes_string(y = i)) +
geom_line() +
scale_y_continuous(labels = comma)
)
}
However, in another plot where I do need the group clause R is failing to recognise the existence of it
for (i in columns)
{
print(
ggplot(demand_year_month, aes(x = year_month) + aes_string(y = i), group = 1) +
geom_line() +
scale_y_continuous(labels = comma)
)
}
because it is throwing the error:
'geom_path: Each group consists of only one observation. Do you need to adjust the group aesthetic?'
My guess is modification of the udf is needed. If so, how? or is there a neater solution? Thank you.

Try puttinggroup = 1in thegeom_line()layer or inside the globalaes().

Just useaes(x = year_month, group=1)or also add+aes(group = 1)(rather than putting it after the comma). Right now you are not passing that as an aesthetic. Right now theggplotfunction just ignores that additional parameter.

Something as simple as that. I can't believe it. Very grateful for your prompt reply @aosmith May I ask how you had this idea? Experience?

@ MrFlick Tried both. Both threw the error: 'Error: geom_line requires the following missing aesthetics: y' Seems y axis has to be mentioned. But thank you for your udf solution.
