error in scatterplot3js

[Selina Carter]

My code for scatterplot3js gives the following error:

Error in scatterplot3js(subset(house_votes_color_Dem, select = c(“aye”, :
(list) object cannot be coerced to type ‘double’

How do I fix this?

I ran exactly the same code as the slide:
scatterplot3js(subset(house_votes_color_Dem,
select = c(“aye”, “nay”, “other”)),
renderer = “canvas”, #<- makes the points round
color = house_votes_color_Dem$color,
flip.y = FALSE, #<- makes the y-axis go from small to
# large values starting from the x-axis
labels = house_votes_color_Dem$Last.Name) #<- shows Rep’s last name
# when you scroll over a point

Hi Selina,

Thank you for your post – it looks like the scatterplot3js has been updated so that it only accepts matrices as the data input (you can view this documentation by entering ?scatterplot3js). This means that we need to put as.matrix in front of the subsetted data, and close it with an extra parenthesis:

scatterplot3js(as.matrix(subset(house_votes_color_Dem, 
                                select = c("aye", "nay", "other"))),
#              renderer = "canvas",    # <- makes the points round
               color = house_votes_color_Dem$color,
               flip.y = FALSE,    # <- makes the y-axis go from small
                                  #    to large values starting from 
                                  #    the x-axis
               labels = house_votes_color_Dem$Last.Name)  # <- shows the 
                                                          #    Rep's name 
                                                          #    when you 
                                                          #    scroll over 

You’ll notice that I also commented out the ‘renderer’ argument, as it seems to have been temporarily disabled by the creator of this package. When you run this code, the chart should appear. Please let me know if that works!

Best,

Merav
