NOTE: It appears that as of ergm
3.6.0, the vertex labels
are been permutted. This will be fixed in the next release.
Sampson (1969) recorded the social interactions among a group of monks while resident as an experimenter on vision, and collected numerous sociometric rankings. During his stay, a political ``crisis in the cloister'' resulted in the expulsion of four monks (Nos. 2, 3, 17, and 18) and the voluntary departure of several others - most immediately, Nos. 1, 7, 14, 15, and 16. (In the end, only 5, 6, 9, and 11 remained). Of particular interest is the data on positive affect relations (``liking''), in which each monk was asked if they had positive relations to each of the other monks.
The data were gathered at three times to capture changes in group sentiment
over time: samplk1
, samplk2
, and samplk3
.
They represent three time points in the period during which a
new cohort entered the monastery near the end of the study but
before the major conflict began.
Each member ranked only his top three choices on ``liking.''
(Some subjects offered tied ranks for their top four choices). A tie from monk A to monk B exists if A nominated B as one of his three best friends at that that time point.
samplk3
is a data set of Hoff, Raftery and Handcock (2002).
See also the data set sampson
containing the time-aggregated
graph samplike
.
It is the cumulative tie for ``liking'' over the three periods. For this, a tie from monk A to monk B exists if A nominated B as one of his three best friends at any of the three time points.
All graphs are stored as network
objects.
They have three vertex attributes:
This data set is standard in the social network analysis literature, having been modeled by Holland and Leinhardt (1981), Reitz (1982), Holland, Laskey and Leinhardt (1983), and Fienberg, Meyer, and Wasserman (1981), Hoff, Raftery, and Handcock (2002), etc. This is only a small piece of the data collected by Sampson.
This dataset was updated for version 2.5 (March 2012) to add the
cloisterville
variable and refine the names. This information is from
de Nooy, Mrvar, and Batagelj (2005).
The original vertex names were:
Romul_10, Bonaven_5, Ambrose_9, Berth_6, Peter_4, Louis_11, Victor_8,
Winf_12, John_1, Greg_2, Hugh_14, Boni_15, Mark_7, Albert_16, Amand_13,
Basil_3, Elias_17, Simp_18.
