question of merging two dataframes
...is that the value of the second column in database A is less than the
value of the second column in database B. Is there a R code to do
this? Thanks
Dataframe A: V1a V2a V3a
1 2 3 5
2 3 4 6
3
Dataframe B: V1b V2b V3b
1 2 5 9
2 9 2 7
Dataframe C should be: V1a V2a V3a V1b V2b V3b
1 2 3 5 2 5 9

Manipulation of longitudinal data by row

Eventually I have to determine mean time to resolution, mean follow-up

beyond my coding skill. Suggestions appreciated.

Repating a loop of lm function with different columns of database
...o wanted to get the p-value in a dataframe with three columns:
Fitst column: analyte name (that´s the name of the column)Second column: pvalue of the first measure of the analte predicting the second measureThird column: The effect of time
I copy a samller example:
txt <- "V1a V2a V3a V1b V2b V3b TimeDifferenceDays2.42 72.4 3.75 2.46 55.4 4.44 6081.66 89.7 2.54 2.17 94.0 2.15 4192.45 112. 0.46 2.40 129.0 .42 7142.58 55.6 5.05 2.44 135.0 5.39 7212.61 332.0 22.6 3.55 238.0 16.4 729"

Mesa with voodoo3
OK I downloaded and compiled Mesa 3.4.1, the gears demo runs at about 140
