Object not found after reading into R

[bshall]

seed_set <- read_excel("seed_set.xlsx")

#seed_set <- as.data.frame(unclass(seed_set),
#stringsAsFactors = TRUE)

class("species")#not found? why
length("species")#not found? why
unique(full) # not found ? why

unique(full)

Error in unique(full) : object 'full' not found

Instead of referencing the column names directly, reference them in relation to the dataframe itself.

class(seed_set$species)
length(seed_set$species)
unique(seed_set$full)

Hope this helps!

Thank you so much! It worked. Why do I need to do that in order for it to read those variables properly?

[BLukomski]

The column names don't exist in R outside of their relation to the dataframe they are a part of. The dataframe itself is a variable, but it's columns are not, so they cannot be referenced in R functions. You could set the columns to be their own variables by doing something like this.

species <- seed_set$species
full <- seed_set$full

But in order to keep things concise and avoid an excess amount of variables, I'd recommend referencing the dataframe each time you need to reference the column.
