Hi, (@FactOREO --this is somewhat related to my previous questions you helped with)
I have a large dataset with multiple parameters, and multiple sampling stations. I want to make plots of every parameter for every station. I can use facet_wrap to create plots for my selected stations. But, how do i repeat this for all parameters, other than typing in the name for each parameter?
Some of my script (the "filter(parm == "pH") %>% is the step I want to automate, and do this for all parms:
## Select stations with adequate data
df2 <- df %>%
filter(station %in% c("23917", "24734", "24764", "24805", "24833", "25020039"))
#> Error in df %>% filter(station %in% c("23917", "24734", "24764", "24805", : could not find function "%>%"
## Plot data
p1 <- df2 %>%
filter(parm == "pH") %>%
ggplot(aes(x = date, y = value)) +
geom_point() +
labs(y = "pH (SU)", x = "Year") +
scale_y_continuous(limits = c(4,10), breaks = c(4, 5, 6, 7, 8, 9, 10)) +
facet_wrap(~station)
#> Error in df2 %>% filter(parm == "pH") %>% ggplot(aes(x = date, y = value)): could not find function "%>%"
p1
#> Error in eval(expr, envir, enclos): object 'p1' not found
