Hi,
I am having a problem with the SparkR API. I need to subset a distributed
data so I can extract single values from it on which I can then do
calculations.
Each row of my df has two integer values, I am creating a vector of new
values calculated as a series of sin, cos, tan functions on these
Here are a few code snippets:
The data frame looks like this:
kfzzeit datum
latitude longitude
1 # 2015-02-09 07:18:33 2015-02-09 52.35234 9.881965
2 # 2015-02-09 07:18:34 2015-02-09 52.35233 9.881970
3 #
I am calling dirs(x, dat) with a number for x and a distributed dataframe for
dat, like dirs(3, df).
With your logical expression Felix I would get another data frame, right?
This is not what I need, I need to extract a single value in a specific cell
for my calculations. Is that somehow possible?
