r - Separate sizes for points and lines in geom_pointrange from ggplot -


using ggplot's geom_pointrange() function, how change size of point , thickness of line separately?

example:

# make test data df <- data.frame(y=10, ymin=1, ymax=20, x=1)  # store ggplot object p <- ggplot(data=df, aes(y=y, ymin=ymin, ymax=ymax, x=x))   # plot 1: big dot , thick line p + geom_pointrange(fill='blue', color='grey', shape=21, size=5)  # plot 2: small dot , thin line (i want small dot , thick line or vice versa) p + geom_pointrange(fill='blue', color='grey', shape=21, lwd=1, size=5)

plot 1:

plot 2:

can small dot thick line (or vice-versa)?

a workaround might plot line , point separate geoms using geom_point , geom_errorbar. unfortunately, real application involves jittering, point , interval end in different places (unless maybe can control jittering?).

i can find similar questions on (like this), don't directly answer one.

thanks!

you can use fatten in combination size:

p + geom_pointrange(fill='blue', color='grey', shape=21, fatten = 20, size = 5)

enter image description here 

p + geom_pointrange(fill='blue', color='grey', shape=21, fatten = .5, size = 5)

enter image description here

s. ?geom_pointrange:

fatten
multiplicative factor used increase size of middle bar in geom_crossbar() , middle point in geom_pointrange().

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...
